Palms and species like the big tree of California were growing side by side with species akin to our own common trees. But in the animal world there were many strange forms. This was the age of reptiles. They domineered on the land, in the air, and in the sea. On the land there stalked huge reptiles fifty and sixty feet long, and, when standing erect, at least thirty feet high.<15> Some of these huge creatures were carnivorous, living on other animals. Others fed on the foliage of trees. In the air, huge reptilian bats, veritable flying dragons with a spread of wings from ten to twenty feet, disported themselves.<16> In the sea there swam great reptilian whales, seals, and walruses.<17> There was a marvelous abundance of reptilian life. At the present day, there are not more than six species of reptiles in the whole world having a length of over fifteen feet, and not more than eighteen species exceeding ten feet in length. But from one limited locality, representing but one era of this age in England, there have been discovered four or five species of carnivorous reptiles twenty to fifty feet long, ten or twelve species of crocodiles, lizards, and swimming reptiles from ten to sixty feet long--besides multitudes of great flying reptiles and turtles. Doubtless similar scenes of animal life were everywhere represented.
The most useful thing that a civilian can do in these busy days is to speak as little as possible, and if he feels moved to write, to confine his efforts to his check book. [Laughter.] But this is an exception to that very sound rule. We do not know the present strength of the new armies. Even if we did it would not be necessary to make it public. But we may assume that there are several battalions in Great Britain which were not in existence at the end of last July, and some of them are in London. Nor is it any part of our national policy to explain how far these battalions are prepared for the work which is ahead of them. They were born quite rightly in silence. But that is no reason why they should continue to walk in silence for the rest of their lives. [Cheers.] Unfortunately up to the present most of them have been obliged to walk in silence or to no better accompaniment than whistles and concertinas and other meritorious but inadequate instruments of music with which they have provided themselves. In the beginning this did not matter so much. More urgent needs had to be met; but now that the new armies are what they are, we who cannot assist them by joining their ranks owe it to them to provide them with more worthy music for their help, their gratification, and their honor. [Cheers.]
The largest telescopes at present in existence are _reflectors_. It is much easier to construct a very large mirror than to construct a very large lens; it is also cheaper. A mirror is more likely to get out of order than is a lens, however, and any irregularity in the shape of a mirror produces a greater distorting effect than in a lens. A refractor is also more convenient to handle than is a reflector. For these reasons great refractors are still made, but the largest of them, the great Yerkes' refractor, is much smaller than the greatest reflector, the one on Mount Wilson, California. The lens of the Yerkes' refractor measures three feet four inches in diameter, whereas the Mount Wilson reflector has a diameter of no less than eight feet four inches.
