- A Tramp Steamer
Perhaps the hardest-working machine ever designed by man, and undoubtedly the most romantic of all steam-driven ships. - A Tubeless, or 'Aerial' Telescope
From an illustration in the Opera Varia of Christian Huyghens. Attempts were made to evade this unwieldiness by constructing them with skeleton tubes. or , indeed, even without tubes at all; the object-glass in the tubeless or "aerial" telescope being fixed at the top of a high post, and the eye-piece, that small lens or combination of lenses, which the eye looks directly into, being kept in line with it by means of a string and manœuvred about near the ground. The idea of a telescope without a tube may appear a contradiction in terms; but it is not really so, for the tube adds nothing to the magnifying power of the instrument, and is, in fact, no more than a mere device for keeping the object-glass and eye-piece in a straight line, and for preventing the observer from being hindered by stray lights in his neighbourhood. It goes without saying, of course, that the image of a celestial object will be more clear and defined when examined in the darkness of a tube. - A Tug Boat
The bows of these boats are often protected by pads to which much wear often gives an appearance of a tangled beard. - A Turret Steamer
These strange vessels are comparatively rare, and seem to be passing away entirely. The turret steamer falls into almost any category. It is built in order to save money on certain port and canal dues and other taxes, and its appearance is perhaps the weirdest of that of any ship, save, perhaps, the antediluvian whalebacks once so common on the Great Lakes. Below the water line these turret steamers are much the same as other freighters, but from there up they are vastly different. Just above the water line their sides are turned in until they are almost a deck. These “decks” run forward nearly to the bow and aft almost to the stern. But the central portion of the ship from bow to stern is raised ten or a dozen feet above these strange side “decks,” which in reality are not decks at all, but only sections of the sides of these strange hulls. - A type of extemporised motor ambulance favoured by the French and Belgians

A vanishing type on the lakes - A Viking Ship
These ships were developed by the Norse sea rovers for use in war, and as the seas they sailed were generally rough their ships had to be seaworthy. The result was a type that still leaves its mark. The seaworthy whaleboats of to-day are very similar in shape. - A Whaleback
A strange type of cargo steamer once common on the American Great Lakes, but gradually disappearing. - A Whaling Bark
With a lookout at the masthead these ships cruised all over the earth in the first half of the 19th Century. - A ‘Charron’ armoured car with machine gun

- Achilles bandaging Patroclus,
A kylix from the Berlin Museum of about 490 b. c. It bears the inscription ΣΟΣΙΑΣ ΕΠΟΙΗΣΕΝ, Sosias made (me), and represents Achilles bandaging Patroclus, the names of the two heroes being written round the margin. The painter is Euphronios, and the work is regarded as the masterpiece of that great artist. The left upper arm of Patroclus is injured, and Achilles is bandaging it with a two-rolled bandage, which he is trying to bring down to extend over the elbow. The treatment of the hands, a department in which Euphronios excelled, is particularly fine. Achilles was not a trained surgeon, and it will be observed, from the position of the two tails of the bandage, that he will have some difficulty when it comes to its final fastening! - Action by Andreas and Nanette (Stein), Streicher Viennese escapement (1794)

Ader next turned to steam-driven craft, and built a series of queer, bat-like machines, which he called “Avions,” one of which is illustrated in Fig. 16. Its wings were built up lightly and with great strength by means of hollow wooden spars, and had a span of 54 feet, being deeply arched. The whole machine weighed 1100 lbs., and was thus far smaller and lighter than Maxim’s mighty craft. To propel it, Ader used a couple of horizontal, compound steam engines, which gave 20 h.p. each and drew the machine through the air by means of two 4-bladed screws. The craft was controlled by altering the inclination of its wings, and also by a rudder, the pilot sitting in a carriage below the planes. In 1890, after its inventor had spent a large sum of money, the machine—which, unlike those of Phillips and Maxim, ran upon wheels and was free to rise—did actually make a flight, or rather a leap into the air, covering a distance of about fifty yards. But then, on coming into contact with the ground again, it was wrecked. Ader’s experiments were regarded by the French Government as being so important that he received a grant equalling £20,000 to assist him in continuing his tests; and this goes to show how, even from the first, the French nation was—by reason of its enthusiasm and imagination—able to appreciate what its inventors were striving to attain, and eager to encourage them in their quest. - Adrift on an ice-floe
Adrift on an ice-floe DeLong caught in the ice-pack, was carried past its northern end, thus proving it to be an island, indeed, but making the discovery at heavy cost. Winter in the pack was attended with severe hardships and grave perils. Under the influence of the ocean currents and the tides, the ice was continually breaking up and shifting, and each time the ship was in imminent danger of being crushed. In his journal DeLong tries to describe the terrifying clamor of Page 209a shifting pack. "I know of no sound on shore that can be compared with it," he writes. "A rumble, a shriek, a groan, and the crash of a falling house all combined, might serve to convey an idea of the noise with which this motion of the ice-floe is accompanied." - Advertisement for phlebotomy and cupping instruments

Airships, like aeroplanes, are being armed with guns and bombs; and their power of raising weights enables them to carry heavy weapons. Large and highly destructive bombs have been tested in the German airships, being released over the sea and aimed at targets in the form of rafts. Latest-type airships also carry guns in their cars; and the Zeppelins have a platform upon the tops of their hulls, reached by a ladder through the middle of the ship, from which a machine-gun can be fired upward. This is a very necessary precaution, and is intended to frustrate the attack of an aeroplane. It would be the aim of the latter, whenever possible, to manœuvre above its big enemy—as suggested in figure —and drop a bomb upon its hull. Hence the construction of the top platform of the airship, from which her gunners can direct a vigorous fire aloft. - Air Pump
- Airliners of the future
By the use of such a machine as this, twenty years hence, we shall be able to spend a week-end in New York, as we do now in Paris or Scotland. Flying at immense heights, and at speeds of 200 miles an hour, these huge aircraft—carrying hundreds of passengers in vibrationless luxury—will pass from London to New York in less than twenty hours. - Albany Run-a-bout, Model 2, 4–6 H.

- Altazimuth Theodolite
The figure represents an altazimuth theodolite of an improved pattern used on the Ordnance Survey. The horizontal circle of 14-in. diameter is read by three micrometer microscopes; the vertical circle has a diameter of 12 in., and is read by two microscopes. In the great trigonometrical survey of India the theodolites used in the more important parts of the work have been of 2 and 3 ft. diameter—the circle read by five equidistant microscopes. Every angle is measured twice in each position of the zero of the horizontal circle, of which there are generally ten; the entire 610number of measures of an angle is never less than 20. An examination of 1407 angles showed that the probable error of an observed angle is on the average ±0″.28 - Amputation below the knee

- An Avro Sea-Plane
The sea-plane, when a flight is made, is launched upon the water down a slipway; then the pilot and his passenger embark, the motor is started, and the propeller draws the machine across the water at a rapidly increasing pace. The floats raise themselves higher and higher upon the water, as the air-planes exercise a growing lift, until they only just skim the surface. And now comes the moment when the airman, drawing back his elevating lever, seeks to raise his craft from the water into the air. At first only the front of the floats rise, the rear sections clinging to the surface; then, in another instant, the whole float frees itself from the water in a scatter of spray, and the craft glides at a gently-sloping angle into the air. It is the aim of builders, by the curve they impart, to make the floats leave the water with as little resistance as possible. In the floats of the Avro will be noticed a notch, or cut-away section, which occurs at about the centre of the float upon its lower side. This is called a “step,” and is to help the float to lift from the water. When the main-planes draw upward, as the craft moves prior to its flight, the floats tend, as has been said, to raise themselves in the water; and as they do so, lifting first towards the bow, there comes a space between the upward-cut “step” and the surface of the water. Into this space air finds its way and, by helping still further to free the float from the surface, aids greatly at the moment when the pilot—operating his hand-lever—seeks the final lift which will carry him aloft.

This ship, while similar in many respects to Columbus’s Santa Maria, has made some advances over that famous vessel. The foremast is fitted to carry a topsail in addition to the large foresail shown set in this picture. On ships somewhat later than this one a small spar was sometimes erected perpendicularly at the end of the bowsprit, and a sprit topsail was set above the spritsail which is shown below the bowsprit here. - An early illustration of the octagonal scarificator

The double mast, shown in this drawing, was in common use in Egypt about 3000 B. C. It is occasionally to be seen on native boats in the Orient to-day. - An Egyptian Ship of the 12th Dynasty
It is possible that ships of this type were able, under ideal conditions, to make a little headway, while under sail, against the wind. It was not for many, many centuries, however, that sailing ships were able definitely to make much headway in that direction. - An English Warship of the Time of Henry V
By the time this ship was built hulls had grown considerably in size over what they had been at the time of William the Conqueror, and the era of lavish decoration was well under way. The numerous decks of this ship were not unusual for the time. - An Eskimo Kayak
These small canoes are made of a light frame covered with skins. - An Eskimo Umiak
This boat is structurally similar to the kayak except that it has no deck. It is a larger boat, and will carry heavy loads and perhaps as many as a dozen people. It is made by covering a frame with skins. - An Experiment of 1924
This ship, designed by a German, is propelled by the wind blowing against the two strange towers. These towers are rotated by a motor with the result that, according to the Magnus law, the pressure of the wind becomes greater on one side of each tower than on the other, thus tending to move the ship. It seems hardly likely, at the time this book goes to press, that this application of a formerly unused physical law will revolutionize the propulsion of ships. - An Experimental Airship
...it was followed in due course by the use of small steam engines and electric motors, which were made to turn propellers such as are used in aeroplanes. For such experimental craft, the rounded form of gas-container was abandoned and a cigar-shaped envelope adopted, pointed at both ends, which could be more easily driven through the air. An airship of a crude and early type is seen here. It was built by an experimenter named Gifford, and in 1852 it flew at the rate of seven miles an hour. A. Gas-containing envelope; B. Car suspended below envelope, which carried the aeronaut and a 3-horse-power steam engine; C. Two-bladed propeller driven by the engine; D.
