Abstract
IT is stated by the New York correspondent of The Times that the 200-inch disk began its 3,300-mile railway journey from Corning, New York, to Pasadena on March 26. It is encased in a steel crate weighing 10 tons, with the face of the disk protected by a 4-inch blanket of cork, and its rim by five layers of heavy felt, and is being carried on edge in a specially designed truck. The weight of the crated disk is supported by steel beams covered with cushions of compressed cork. The accompanying illustration (Fig. 1), reproduced from the article by Dr. George E. Hale on the 200-inch telescope which was published as a Supplement to NATURE of February 8, will bring home better than words the transport difficulties involved. The train will not travel faster than 25 miles an hour; the greatest care will have to be exercised, because the bottom edge of the crate is only six inches above the level of the rails, and at certain tunnels and bridges the top will have a clearance of only three inches. The news of the safe arrival of the disk at Palomar Mountain will be awaited with anxiety.
