- A Minute Portion of the Pulp of the Spleen
A Minute Portion of the Pulp of the Spleen,very highly magnified. Stellate connective-tissue cells form spaces containing red blood-corpuscles and leucocytes. In the centre of the diagram is shown the mode of origin of a venule. It contains two phagocytes—the upper with a nucleus, two blood-corpuscles just ingested, and one partially digested in its body-substance; the lower with two blood-corpuscles. - Red Blood-Corpuscles presenting, some the Surfaces, others the Edges, of their Discs, together with Single Representatives of Four Types of Leucocyte.
A, the most common type, highly amœboid and phagocytic. Its protoplasm is finely granular, its nucleus multipartite. B, a leucocyte closely similar to the last, but larger, and containing an undivided nucleus. It is shown with a cluster of particles of soot in its body-substance. C, a young leucocyte, or “lymphocyte.” D, a coarsely granular leucocyte. Its granules stain brightly with acid dyes—e.g., eosin or acid fuchsin. - Page Frame

Divider - A type of camp fire that will burn all night
A type of camp fire that will burn all night To make a fire that will burn in front of the tent all night, first drive two green stakes into the ground at a slant and about five feet apart. Then lay two big logs one on each side of a stake to serve as andirons. Build a fire between these logs and pile up a row of logs above the fire and leaning against the stakes. You may have to brace the stakes with two others which should have a forked end. When the lower log burns out the next one will drop down in its place and unless you have soft, poor wood the fire should burn for ten hours. With this kind of a fire and with a leanto, it is possible to keep warm in the woods, on the coldest, night in winter. - A Section approximately at Right Angles to the Long Axis of the Heart
A Section approximately at Right Angles to the Long Axis of the Heart, exposing the Four Valves which lie very nearly in the Same Plane. The semilunar valve which guards the aperture of the pulmonary artery is the nearest to the breast-bone. - Digestive system in humans
The stomach has been cut across a short distance from the pyloric valve, and removed, to show the viscera which lie behind it. The descending aorta and the vena cava rest upon the vertebral column. They are crossed by the pancreas and the transverse portion of the duodenum. The head of the pancreas is enclosed by the curvatures of the duodenum. The ducts of the liver and pancreas are seen entering the descending duodenum side by side. - Biceps Muscle in Action
The power of muscle varies as its cross-section. For human muscles the maximum lift amounts to from 7 to 10 kilogrammes for each square centimetre. This is a large figure, but it must be remembered that, owing to the arrangement of the bones as levers, most muscles act at a great mechanical disadvantage. The greater the difference in distance from the fulcrum between the point of application of the force and the point of incidence of the weight, when the force acts nearer to the fulcrum than the weight, the greater is the mechanical disadvantage. The greater also is the rapidity with which the weight is lifted. What is lost in strength is gained in swiftness - Divider
Divider - Baseball pitches
Left to right - The In-Curve, the out-curve, the drop and the out-drop The pitcher is the most important member of a ball team. Most of the work falls to him, and a good pitcher, even with a comparatively weak team behind him, can sometimes win games where a good team with a weak pitcher would lose. A good pitcher must first of all have a cool head and keep his nerve even under the most trying circumstances. He must also have good control of the ball and be able to pitch it where he wants it to go. After that he must have a knowledge of curves and know how by causing the ball to spin in a certain way to cause it to change its course and thus to deceive the batsman. The art of curving a ball was discovered in 1867. Before that time all that a pitcher needed was a straight, swift delivery. The three general classes of curved balls used to-day are the out-curve, the in-curve, and the drop. There are also other modifications called "the fade away," "the spitball," and others. Curve pitching will only come with the hardest kind of practice. - The Diaphragm and Organs in Contact with it
The Diaphragm and Organs in Contact with it—A, in Expiration; B, at the End of a Deep Inspiration. Transverse Vertical Sections in the Line of the Armpit. A, At the end of an ordinary expiration the lung does not extend below the upper border of the eighth rib. From this level to the middle or lower border of the tenth rib the two layers of the pleura covering respectively the inner wall of the chest and the upper surface of the diaphragm are in contact. B, When the lung is distended with air it occupies the whole of the pleural cavity. - Stylized Flower Divider

A chicken coop for grown fowls can be of almost any shape, size, or material, providing that we do not crowd it to more than its proper capacity. The important thing is to have a coop that is dry, easily cleaned and with good ventilation, but without cracks to admit draughts. A roost made of two by four timbers set on edge with the sharp corners rounded off is better than a round perch. No matter how many roosts we provide, our chickens will always fight and quarrel to occupy the top one. Under the roost build a movable board or shelf which may easily be taken out and cleaned. Place the nest boxes under this board, close to the ground. One nest for four hens is a fair allowance. Hens prefer to nest in a dark place if possible. A modern, up-to-date coop should have a warm, windproof sleeping room and an outside scratching shed. A sleeping room should be provided with a window on the south side and reaching nearly to the floor. - Potted plant divider

A rabbit hutch or coop is easily built from old packing boxes. One third of the coop should be darkened and made into a nest, with an entrance door outside and the rest simply covered with a wire front, also with a door for cleaning and feeding. The hutch should stand on legs above ground as rabbits do not thrive well in dampness. They will, however, live out all winter in a dry place. A box four feet long and two feet wide will hold a pair of rabbits nicely. Rabbits will become very tame and may often be allowed full liberty about the place if there are no dogs to molest them. The drawing shows a standard type of rabbit hutch. A boy who is handy with tools can easily build one. We can always dispose of the increase in our rabbit family to friends or to dealers. - Man Lion

The beast par excellence of Egypt is the donkey; he ought to have a place on the national coat-of-arms, as much so as the llama has on that of Peru. The horses of Egypt are magnificent, some of pure Arabian, and some of a cross between English and Arabian stock, and are famous for their speed and beauty. But they are a luxury that not everybody can afford, as their support requires a constant outlay, not to speak of the first cost of the property. But the donkey is universal, and everybody can have one, unless he is the poorest of the poor. At every hotel door there are groups of them ready saddled at all hours of the day, and you can hire them cheaply. If you can make a bargain in advance you can hire a donkey at three or four francs a day, inclusive of the boy, to drive him, though the latter generally looks for backsheesh in addition to the price of the beast and saddle. I have hired donkeys frequently for half a franc an hour, though the hotel keepers tell you that a franc an hour is the proper fare. - Raft bouyed by inflated skins (ancient)

- A reflector camp oven
There are several kinds of ovens used for baking bread and roasting meat in outdoor life. The simplest way is to prop a frying pan up in front of the fire. This is not the best way but you will have to do it if you are travelling light. A reflector, when made of sheet iron or aluminum is the best camp oven. Tin is not so satisfactory because it will not reflect the heat equally. Both the top and bottom of the reflector oven are on a slope and midway between is a steel baking pan held in place by grooves. This oven can be moved about at will to regulate the amount of heat and furthermore it can be used in front of a blazing fire without waiting for a bed of coals. Such a rig can easily be made by any tinsmith. A very convenient folding reflector oven can be bought in aluminum for three or four dollars. When not used for baking, it makes an excellent dishpan. - Gazing through the doors of the cupboard
'Christoph, I wish you would let me have that book of manuscript music which you have in your cupboard—the one which contains pieces by Pachelbel, and Frohberger, and Buxtehude, and ever so many others—you know which I mean. I will take such care of it if you will only lend it to me for a little while.' Christoph was about to leave the room, but he turned sharply to his little brother as the latter put his request. 'No, Sebastian, I will certainly not lend you the book, and I wonder that you have the impertinence to ask me such a thing! The idea of your thinking that you could study such masters as Buxtehude and Frohberger—a child like you! Get on with what I have set you to learn, and do not let me hear any more of such fancies!' With that Christoph shut the door behind him, and Sebastian was left to ponder sadly upon his elder brother's harshness in refusing to accede to his simple request. The disappointment was very keen, for little Sebastian had been longing to get possession of that precious volume. For several days past he had spent hours in his brother's absence gazing at its covers through the lattice doors of the cupboard, and feasting his eyes upon the names of the musicians which were written on the back in bold letters in Christoph's hand. - The football uniform

An Indian tepee - By the light of the moon he began his task
Bach copying from his brothers book which he 'borrowed' Then, taking his pen and some manuscript music-paper with which he had provided himself, he began his task of copying out the pieces contained in the book. An hour or more slipped away in this absorbing occupation, and it was not until the moon had shifted her position, so that her rays no longer afforded the necessary light, that Sebastian ceased to ply his pen. Then, having hidden the book away and removed all traces of his work, the now wearied little musician sought his pillow and fell fast asleep. - Plan of Harpers Ferry Bridge
Shortly after the Harpers Ferry bridge reconstruction, Bollman was made foreman of bridges. It is apparent that, on the basis of his practical ability, enhanced by the theoretical knowledge gained by intense self-study, he eventually came to assist Chief Engineer Benjamin H. Latrobe in bridge design. He later took this work over entirely as Latrobe’s attentions and talents were demanded in the location and extension of the line between Cumberland and Wheeling. - The Story Teller of the Desert
The Story Teller of the Desert - Section of First-rate Man-of-War
I will now give you a sectional division of a first-rate line-of-battle ship. Such a ship, carrying 120 or more guns, has four decks on which her guns are placed. The highest is open to the air, and is called the UPPER DECK At the after part, extending a little way beyond the mizen-mast, there is a raised platform, called the POOP. It has no guns on it. On the main deck is the steering-wheel, with the binnacle in front of it. The after part of this deck between the poop and the main-mast is called the quarter-deck, and is the place where the officers especially walk. The part under the poop is divided into cabins, appropriated to the use of the captain. Here, also, is a clerk's office and a pantry. Between the main and fore-mast the large boats are stowed, and on either side are the gangways at which sentries are stationed. The next deck under this is called the MAIN DECK. In the after part is the admiral's cabin. Immediately under the boats is a pen for the officers' live-stock ; and just abaft the fore-mast is the galley, or kitchen. The third deck from the upper is called the MIDDLE DECK. The after part is fitted up for the lieutenants, chaplain, surgeon, paymaster, marine officers, &c., and called the WARD-ROOM. In the fore part of the deck is placed the sick-bay, a compartment fitted up as a hospital ; about the centre of this deck is one of the capstans. The fourth from the upper is called the LOWER or GUN DECK. In the after part is the GUN-ROOM, where the midshipmen, and other junior officers, mess. The tiller of the rudder works through the gun-room just above their heads. A second capstan is placed on this deck ; and forward are the riding-bitts for securing the cables. It is the lowest deck on which guns are carried. The ORLOP DECK is the fifth deck from the upper. It has no guns or ports, though lighted up by bull's eyes or scuttles. In the after part is the purser's issue-room ; next to it is the after cockpit, where the midshipmen and other junior officers sleep in hammocks. Before it again will be found the sail-room, where the sails are kept, and the cable-tiers, where the cables are stowed. Before it again, just abaft the fore-mast, is the fore cockpit, and the warrant officers' cabins, while right in the head of the ship are the carpenter's and boatswain's stores. Low as we have got, we have still further to go down to the HOLD, which, if it may be so called, is the sixth deck from the highest. It is often divided into two decks for the greater convenience of stowage. Here are the FORE AND AFTER MAGAZINES, WATER TANKS, WINE AND SPIRIT ROOM, CHAIN CABLE LOCKERS, SHOT LOCKERS, BREAD ROOM, SHELL ROOM, GUNNER'S STORE ROOM, DRY PROVISION, and BEEF AND PORK IN CASKS. Since the introduction of auxiliary steam-power into ships of war, a large portion of the hold is devoted to the steam-engine and boilers, coal bunkers, and the shaft of the screw, while the funnel runs up through all the decks ; but it is wonderful, comparatively, how little space these are allowed to occupy, considering the great aid the steam-engine affords to the movements of the ship. - The 'Minotaur'
Launched in 1863 Among the numerous huge monsters constituting the iron-clad fleet of England, the Minotaur, is one of the most gigantic and formidable; and the sister ships, the Agincourt and Northumberland, all of precisely the same tonnage, power, rig, and equipment, are the largest and most powerful ships in the navy. The Minotaur was built at Blackwall, by the Thames Ship Building company and the engines were constructed by Messrs. Penn, of Deptford. She is 6,621 ton's measurement, and propelled by screw engins of 1,350 horsepower, with a speed of 15 knots an hour. She is 400 feet in length by 59 in width, and carries in all thirty-four of the heaviest guns used afloat. Among these which form her chief batter on the main deck are four 300-pounder Armstrongs. - “Backsheesh, O, Howadji!”
One of our favorite amusements at each landing-place was to make the natives scramble for money. They came down in large numbers, sometimes two or three hundred of them, and kept up a continual howl of “Backsheesh, O, Howadji!” that sounded very much like the murmurs of a mob. They gathered on the bank opposite the stern of the boat, and were ready to catch all the money we would throw to them. We had a supply of copper for just such cases, and by a judicious use of it, we made a franc go a great ways, and this was the way we would distribute it. One of us would take a copper, and after balancing and aiming it several times, would give it a toss. A mass of hands would be stretched to receive it, and the crowd would sway in the direction of the falling coin. If it struck in the dirt, a dozen Arabs would spring upon the place where it fell, and there would be a scramble for it. Sometimes the struggle would be so fierce, that the cloud of dust raised thereby would completely conceal the combatants, and they would emerge with torn garments - The Egg of Creation

Patent Iron Suspension Railroad Bridge. The undersigned would inform the officers of Railroads and others, that he is prepared to furnish Drawings and Estimates for Bridges, Roofs, etc., on the plan of Bollman’s Patent. The performance of these bridges, some of which have been in use for six years, has given entire satisfaction. Their simplicity of construction renders repairs easy and cheap, and by a peculiar connection of the Main and Panel Rods at the bottom of the Posts, all danger from the effects of expansion, which has heretofore been the chief objection to Iron Bridges, is entirely removed. J. H. TEGMEYER, Baltimore, Md. - Truth
The four figures in the Vignette are intended to represent the chief protestant reformers; Luther in the centre, Cranmer on his right hand, Knox on his left, and Calvin on his extreme right; each holding in his hand a manuscript or printed copy of the Word of God. the Rock on which they are standing, is intended to denote the Truth of the doctrine of the Divine Oracle, on which, as on an immutable Rock, the Reformers rested all their claims, in labouring to restore pure Christianity. Around the Rock of Truth, the waves of Error and Superstition are seen dashing.
