For this purpose the party of Professor Renwick was furnished with the following barometers: Two loaned by the Superintendent of the Coast Survey, of his own construction; two portable and one standard, by Neurnan; three of the siphon form, by Buntin, of Paris; one by Traughton & Simms; one by Forlin, of Paris; three of siphon form, by Roach & Warner, of New York; two by Tagliabue, of New York, originally on the plan of Durand, but which had been advantageously altered by Roach & Warner in such manner as to admit of the adjustment of the level of the mercury in the cistern.
At once, as if all the houses on the street were toy barometers, every door swung open and a stream of men and boys in dirty shirts and overalls flowed out through the squalid yards along the sidewalks toward the factory.
The observations with the barometers were speedily taken, which gave the height of Banajao as six thousand five hundred feet. The trees on the summit were twenty or thirty feet high, and a species of fir was very common. Gaultheria, attached to the trunks of trees, Rhododendrons, and Polygonums, also abounded.
Then a few turns of the thumb-screw bring the spring to bear upon the box, its walls expand until the pressure of the spring equals the pressure of the atmosphere, the reading is taken, and the instrument thrown out of operation again a most ingenious arrangement by which it was hoped to overcome some of the persistent faults of elastic-chamber barometers.
Her photograph, the only picture on the porch, held her attention. It hung under his barometers and thermometers, which, she knew, was where he looked oftenest. A fancy came to her, and she turned the laughing face to the wall and glanced from the blankness of the back of the frame to the bed and back again. With a quick panic movement, she turned the laughing face out.
Overhead hung an ordinary tell-tale compass, and compactly placed on other parts of the wall were barometers, thermometers, barographs, and, in fact, practically every instrument that the most exacting of aeronauts or Space-explorers could have asked for.
We could not verify this estimate of the height, the surf not having permitted us to return on board during the night, to take our barometers and dipping-needle. As we foresaw that our expedition to the peak would be very precipitate, we consoled ourselves with the reflection that it was well not to expose instruments which were to serve us in countries less known by Europeans.
Enormous blocks of white and red stratified quartz, and slate, some 20 and even 40 yards long, rest on the narrow ridge at 7000 feet elevation. I hung the barometers near one of the many chaits on the summit, where there is also a rude temple, in which worship is performed once a year.
Now the basket is attached, the barometers are brought, the siren, which we will blow to our hearts' content, is also brought, also the two trumpets, the eatables, the overcoats and raincoats, all the small articles that can go with the men in that flying basket. As the wind pushes the balloon against the gasometers, it is necessary to steady it now and then, to avoid an accident at the start.
Then there are those new style of barometers, the long straight ones. I never can make head or tail of those. There is one side for 10 a.m. yesterday, and one side for 10 a.m. to-day; but you can't always get there as early as ten, you know. And you've got to correct it to sea-level, and reduce it to Fahrenheit, and even then I don't know the answer. But who wants to be foretold the weather?
