No certain estimates or the distances, terrestrial standards, can be made, but it is usual to take the "light-year" the distance light would go in one year, as a unit, if we assume that the faintest stars seen with the column are 45,000 light-years away, then the 100-inch should show, that are 72,000 light-years away. A light-year is about 5,800,000,000,000 miles. In other words, we may say that the new giant will expand the telescopic boundaries about 50,000 miles on every side below their present limits!

An authoritative statement of some of the things that may be expected of the new telescope and of the investigations to which it is matchless powers will be applied, is presented in the interview with Professor George K. Hale, the director of the Mount Wilson Observatory. The work carried on at that observatory is the most important astronomical work now being done on the earth, and its results will be enormously enhanced in value by bringing the new instrument into action. One, however, regrets that there is no prospect of half a dozen similar telescopes in order that all the different branches of investigation that might be advanced by them could be undertaken simultaneously.
