According to report from New York the German trans-Atlantic plane Nórdmeer arrived Port Washington, the seaplane harbour of New York this evening, having covered the distance from Horta on the Azores, a stretch of 3,850 kin., in seventeen hours twelve mjnutes—Trans-Ocean.
The world's second largest telescope, constructed by Sir Howard Grubb, Parsons & Ca, Ltd, Walker-gate-on-Tyne and the result of two years Tyneside craftsmanship—will leave Newcastle within the next few months for the new Radcliffe Observatory in Pretoria, South Africa.
Costing about £40,000, the telescope has been constructed at Walkergateon-Tyne, and it has a "great" mirror, 74 inches in diameter, weighing two tons. Months of work are involved in the production of this mirror. Made of Pyrex glass it is ground spherical and then polished in the shape of a parabola. Smaller mirrors used in the giant telescope are made of fused quartz. Accuracy on the construction of the telescope with its mirrors and movements requires to be to one millionth of an inch.
The instrument will be housed in a steel turret, 61 feet in diameter, and the tube, made of dur aluminium, is 35 feet long. Although the moving parts alone weigh some 35 tons, the whole apparatus can be worked by the touch of push buttons. Eighteen motors are used in operating the telescope, and the other equipment, in addition to spectroscopic arrangements, includes a special camera which has two guiding microscopes.
