Jeff called and signaled that all was ready. Larry summoned Sandy but the latter lingered, while Dick, a little sorry he had taunted so much, followed Larry toward the waiting airplane. But Sandy, scowling, hesitated whether he would go or be angry and refuse to join the Sky Patrol. Then, as he clambered onto the forward bracing of the under wing and leaned on the cockpit cowling, his face assumed a startled, intent expression.The latter seems a plausible theory, and perhaps a correct one; but there are two facts in connection with the operation of reaction water-wheels which seem to controvert the latter and favour the first theory, namely, that reaction wheels in actual practice seldom utilise more than forty per cent. of useful effect from the water, and that their speed may exceed the initial velocity of the water. With this the subject is left as one for argument or investigation on the part of the reader.
Possibly the world may move, and possibly it may be at rest. Possibly it may be round, or else it may be triangular, or have any other shape. Possibly the sun and the stars may be extinguished at setting, and be lighted afresh at their rising: it is, however, equally possible that they may only disappear under the earth and reappear again, or that their rising and setting is due to yet other causes. Possibly the waxing and waning of the moon may be caused by the moons revolving; or it may be due to the atmospheric change, or to an actual increase or decrease in the moons size, or to some other cause. Possibly the moon may shine with borrowed light, or it may shine with its own, experience supplying us with instances of bodies which give their own light, and of others which have their light borrowed. From these and such like statements it appears that questions of natural science in themselves have no value for Epicurus. Whilst granting that only one natural explanation of phenomena is generally possible, yet in any particular case it is perfectly indifferent which explanation is adopted.169The passionate despair of the tones touched Ren. It did not seem possible to the man that this woman was acting.It was an imposing sight to see all these various divisions in their brilliant uniforms coming down along the road, the soldiers' uniforms still without a stain, the horses in new, fine, strong leather harness, and the rumbling and jolting guns. The soldiers sang patriotic songs, and among them rode the officers, proud and imperious, many with a monocle, looking round superciliously.This makes a statement in brief of what comprehends a knowledge of pattern-making, and what must be understood not only by pattern-makers, but also by mechanical engineers who undertake to design machinery or manage its construction successfully.I had also to promise the major that on my return I should bring with me a copy of De Tijd in which all I had experienced and seen in Bilsen was described, and also a box of Netherland cigars, which he promised to pay for; then I was allowed to go.
