A Dog that Knew a Tune.
Does your dog know a tune? In Trenton, New Jersey, two famous dogs are owned. One is said to be worth $200. Some months ago both were stolen. All attempts to find them were in vain, and money rewards proved unavailing. Recently the owner went to a barn where he thought they might be. He whistled, but got no response. He was just leaving the premises when he recalled that one of the dogs always showed unusual life and joy whenever he whistled the tune, popular years ago, under the title "Captain Jinks," who belonged to certain marines. He whistled this tune at a venture, and was at once rewarded by a vigorous whine which he readily recognized. The dog knew the tune, and the result was the recovery by the owner of his two valuable dogs, and the arrest of the thief who had stolen them.
The Largest Lens.
The largest telescopic lens ever made has just been completed in Cambridgeport, Massachusetts. It cost $100,000, and is the property of the Chicago University, for use in the observatory on Lake Geneva, Wisconsin. This lens is the greatest work of its kind ever undertaken in the world. Day and night, not a single minute has the lens been neglected. Every precaution was taken to insure its safety from damage, and now that the work is finished, it only remains to carefully ship it to its destination.
Once it safely arrives at Lake Geneva, the huge lens will be placed in the telescope of what is known as the Yerkes Observatory. The dome of the observatory is 110 feet high and ninety feet in diameter. Its weight is about 200 tons. It revolves on twenty-six sets of ball-bearing wheels, and is worked by electricity. Beneath the dome is a marble floor hung with counter-balance weights. This floor, ponderous as it appears, can be raised or lowered twenty-five feet, at the will of the observer, by the simple turning of a lever.
