Mills's visit was that in December, 1874, I was invited to visit the European workshops as an agent of the Lick trustees, with a view of determining whether there was any chance of getting the telescope made abroad. The most difficult and delicate question arose in the beginning; shall the telescope be a reflector or a refractor?
For facilitating cleaning, the lamps are arranged so as to turn on a hinge-joint, m; so that, on removing the reflector, o, it is only necessary to raise the arm that carries the burner, r in order to clean the base, s, without any difficulty. But one of the most interesting applications of oil is that of in which case it is compressed into large reservoirs placed on a boat.
This explanation restored my good humour, and as I could not quit my companion, and he did not feel disposed to leave me, I made up my mind to travel with him to Fort Lawrence, the limit of HIS CIRCUIT. No. The Clock Maker. The house of every substantial farmer had three substantial ornaments, a wooden clock, a tin reflector, and a Polyglot Bible.
The only thing at all peculiar about the room and its appointments was a reflector, ingeniously arranged above the chandelier in such a way as to throw the full glare of the candles upon the card-table which stood directly beneath it.
But Lord Rosse's 6-foot reflector, 54 feet focal length, constructed in 1845, is still the largest ever made. The imperfections of our atmosphere are against the use of such large apertures, unless it be on high mountains. During the last half century excellent specula have been made of silvered glass, and Dr.
Still, large telescopes, as a rule, held aloof for some unexplained reason, or were only employed in a desultory and spasmodic fashion, without any very definite object. Birt, the largest instruments available being an 8 1/4 inch reflector and the Crossley refractor of 9 inches aperture!
The Nautilus, Captain Nemo explained, was capable of a speed of fifty miles an hour, and could be made to sink or rise with precision by flooding or emptying a reservoir. In a box, raised somewhat above the hull and fitted with glass ten inches thick, the steersman had his place, and a powerful electric reflector behind him illumined the sea for half a mile in front.
According to the calculations of the Cambridge Observatory staff, the tube of the new reflector was to be 280 feet long and its mirror 16 feet in diameter. Although it was so colossal it was not comparable to the telescope 10,000 feet long which the astronomer Hooke proposed to construct some years ago. Nevertheless the setting up of such an apparatus presented great difficulties.
"I didn't know but it would be a good place to hide our plate and other treasures," said Marta, offering rather methodically the first invention that came to mind as she threw open-the reflector of the lantern and turned down the wick. She was ashamed of the excuse. It warned her how easy it was becoming for her to lie yes, lie was the word. "Don't blow out the light, please," said Mrs. Galland.
Ruby divided his time between the kitchen and lantern, lending a hand in each, but, we fear, interrupting the work more than he advanced it. That day it fell calm, and the sun shone brightly. "We'll have fog to-night," observed Dumsby to Brand, pausing in the operation of polishing a reflector, in which his fat face was mirrored with the most indescribable and dreadful distortions.
