73 INVERTED CYLINDER RILL ENGINES The Lick Observatory. Francisrc-aud- invested in real estate astronomical observations. Mount as being the proper location. This mountain has a summit about 4500.feet high and is located about fifty miles southeast of San Fran cisco. About 45000 tons of rocks in abundance were used to make plain the lec turer's remarks although the lecture itself was very comprehensive and unusually clear. Illustrations and ground plans of the site and its approach were all highly instructive in connection with the explana tions. hridgepork ft% years ago. They have just completed the work assigned to them and the glass has been 4ransferied by palace car to the observatory. The prOspeetive capabilities of the large telescope are twit log astronomers to a state of high tension. They ex pect to employ a power of 8500 diameters on the in strument when the weather is most favorable and the theoretical distance of the moon would then become about 60 miles. Making due allowance for the unavoid able effects of the earth's atmosphere and other un favorable conditions the observer might expect to see the moon much the same as he would without the tele scope if it were only a hundred miles away. If at the same time the moon happened to be at its least dis tance from the observer about 220000 miles and if the IMPROVED COMPOUND MILL ENGINE. objects on the moon were suitably illumined by the sun's light it is possible that details of its nature might be satisfactorily made out even although they were no larger than the national Capitol building at Washing ton. The location of the observatory in a region which is entirely cloudless during the greater part of the year constitutes an advantage which only those an fully appreciate whose work has suffered serious interrup tion from the lack of a continuously clear sky. The peak of the mountain stands above the clouds nearly all the time and a series of pictures were shown.repro clueing the startling effect of the sea
