Seite 118 - Campaign, not as a tragedy, nor as a mistake, but as a great human effort, which came, more than once, very near to triumph, achieved the impossible many times, and failed, in the end, as many great deeds of arms have failed, from something which had nothing to do with arms nor with the men who bore them.
Seite 234 - The canal shall be free and open to the vessels of commerce and of war of all nations observing these Rules, on terms of entire equality, so that there shall be no discrimination against any such nation, or its citizens or subjects, in respect of the conditions or charges of traffic, or otherwise.

Seite 231 - drift line," or true course. MOVEMENTS OF THE WAVE CRESTS As a still further refinement in ascertaining speed and direction, account should be taken of the movement of the wave crests themselves. This can ordinarily be found by determining the length between the crests, inasmuch as the velocity varies about as the square root of the wave length or distance between crests; the velocity in feet per second equals the wave length in feet at a point where each is expressed by the figure 5...
Seite 229 - ... with it, but, as a matter of fact, the wave crests are clearly visible. Fig. 8 is a reproduction of a photograph taken from a considerable altitude, and shows how clearly visible these wave crests are. They are an excellent indicator of two valuable factors: First, from their length from crest to crest we can ascertain their speed; and second, their direction always lies directly normal to that of the wind. In all probability there also exists a reasonable relation between the velocity of the...
Seite 228 - ... from the longitudinal axis of the aircraft indicated by the zero on the scale shown on the bezel. When the observer and the pilot sit in tandem relation in the aircraft, then it becomes desirable that each have a compass. We have made a number of sets, Fig. 6, in which two compasses are synchronized by means of a single drift indicator. Precautions in Flight Over Water We will now turn our attention to some refinements of the use of this apparatus when one is flying under actual service conditions...
Seite 269 - Copy must contain nothing to indicate its authorship, must be signed with a nom de plume, and must be accompanied by a sealed envelope containing this nom de plume and the name of the writer. This envelope will remain in the hands of the Editor of the JOURNAL and, after award has been made by the Committee, will be opened in the presence of the Coast Artillery School Board.
Seite 66 - The history of war will show, almost without exception, that each great conflict has resulted In the introduction of new and powerful weapons and devices for attack and defense. Initial advantages of immense import have been gained by a belligerent who has developed some new innovation against which no immediate defense was adequate. The innovation of yesterday becomes the necessity of to-morrow. The present gigantic conflict waging in Europe is too near In perspective and too obscure in detail to...
Seite 400 - ... in service for 100 rounds and then returned for examination. The result is shown in Fig. 14, which is the letter V impressed at 5,000 Ib. It will be noticed that the transformation has proceeded to its final stage, viz., the light etching structure which had previously been shown to be martensite.7 These experiments seem to prove that the hardness of the surface of a gun tube as well as the pressure plug is due to a combination of mechanical deformation and a process of martensitization. This...
Seite 119 - ... he has done with life, tasted and spoken and loved his last, and that in a few minutes more may be blasted dead, or lying bleeding in the scrub, with perhaps his face gone and a leg and an arm broken, unable to move but still alive, unable to drive away the flies or screen the everdropping rain, in a place where none will find him, or be able to help him, a place where he will die and rot and shrivel, till nothing is left of him but a few rags and a few remnants and a little identificationdisc...
