Observatory Without Telescopes.

The Carnegie observatory on Mount Wilson, in California, is of white canvas, like some huge ark. You look for telescopes inside, but in vain; a series of mirrors appear instead, and it is the third of these that does the magnifying instead of the usual telescope tube. Visitors are accommodated in chalets, a little house being apportioned to each guest. Observations have been carried on since April, 1964, and every day a photoheliograph is taken and several other pictures by means of the spectrohellogram.—London Globe.
