Hence we find him first making brass scales, parallel-rulers and quadrants. By the end of one month in this department he was able to finish a Hadley quadrant. From this he proceeded to azimuth compasses, brass sectors, theodolites, and other delicate instruments.
These latter have been grouped in the four quadrants, a much more effective arrangement than the cylindrical layer of the schematic worm. Furthermore, the animal has on each segment a pair of fin-like projections, stiffened with bristles, the parapodia. These are moved by special muscles and form effective organs of creeping.
The stock-in-trade of this old gentleman comprised chronometers, barometers, telescopes, compasses, charts, maps, sextants, quadrants, and specimens of every kind of instrument used in the working of a ship's course, or the keeping of a ship's reckoning, or the prosecuting of a ship's discoveries.
When Roger saw the Captain and his mates bring up their quadrants on deck just before noon to make an observation, he brought up his, and began in a methodical way to make preparations for taking one also. "What, youngster, have you been at sea before?" asked the Captain. "No, sir, but I have studied navigation, and I want to put my knowledge into practice."
Noah treated this idea with great disrespect. He could see no use in wearing out quadrants without any necessity for it. Our course was south, we knew, for we were bound to the south pole; all we had to do was to keep America on the starboard, and Africa on the larboard hand.
These include, in cases 10, 11, Nubian and Abyssinian baskets; Arabic quadrants; Egyptian water-bottles; sandals, and a variety of other manufactures from Ashantee, including a shuttle, and specimens of native cotton cloth; an iron bar used as a medium of exchange, and worth about one shilling on the African coast; gourd boxes and calabashes; cloths and other curiosities collected on the Niger Expedition; specimens of native silk from Egga; a skin bottle for holding galena to colour the eyelids; opaque glass beads from Abyssinia; all kinds of arms from French Guiana, Fernando Po, Abyssinia, and Nubia, including a Nubian spear, enveloped with a snake's skin from Thebes.
The use of quadrants, telescopes, and maps on Mercator's projection all began in the reign of Elizabeth, as did many other inventions, adaptations, handy wrinkles, and vital changes in strategy and tactics.
This at last accomplished, he turned round to the Baron, and, changing the huge key about backwards and forwards in his hands, replied with a peculiar smile, "Yes, there are thousands and thousands down there all my dear dead master's beautiful instruments telescopes, quadrants, globes, dark mirrors, they all lie smashed to atoms underneath the ruins between the stones and the big balk."
The rim of these modern sacred vessels commonly bears, in its four quadrants, terraced elevations representing rain-clouds of the cardinal points, and the outer surface of the bowl is decorated with the same symbols, accompanied with tadpole or dragon-fly designs. One of the best figures of the dragon-fly is seen on the saucer shown in plate CXX, f.
The most complicated of all the star-shape figures, like the simplest, takes us to sun emblems, and it seems probable that there is a relationship between the two. Plate CLXI, f, represents four bundles of feathers arranged in quadrants about a rectangular center.
