And their mathematical science as applied to such purpose is so nicely accurate, that on the report of some observer in an air-boat, any member of the vril department can estimate unerringly the nature of intervening obstacles, the height to which the projectile instrument should be raised, and the extent to which it should be charged, so as to reduce to ashes within a space of time too short for me to venture to specify it, a capital twice as vast as London.
Certainly these Ana are wonderful mathematicians--wonderful for the adaptation of the inventive faculty to practical uses.
I went with my host and his daughter Zee over the great public museum, which occupies a wing in the College of Sages, and in which are hoarded, as curious specimens of the ignorant and blundering experiments of ancient times, many contrivances on which we pride ourselves as recent achievements.

In one department, carelessly thrown aside as obsolete lumber, are tubes for destroying life by metallic balls and an inflammable powder, on the principle of our cannons and catapults, and even still more murderous than our latest improvements.
My host spoke of these with a smile of contempt, such as an artillery officer might bestow on the bows and arrows of the Chinese.

In another department there were models of vehicles and vessels worked by steam, and of an air-balloon which might have been constructed by Montgolfier.
"Such," said Zee, with an air of meditative wisdom--"such were the feeble triflings with nature of our savage forefathers, ere they had even a glimmering perception of the properties of vril!" This young Gy was a magnificent specimen of the muscular force to which the females of her country attain.

Her features were beautiful, like those of all her race: never in the upper world have I seen a face so grand and so faultless, but her devotion to the severer studies had given to her countenance an expression of abstract thought which rendered it somewhat stern when in repose; and such a sternness became formidable when observed in connection with her ample shoulders and lofty stature.

She was tall even for a Gy, and I saw her lift up a cannon as easily as I could lift a pocket-pistol.
