A comparatively small and ill-made engine, worked at high pressure, will do more than a large and well-finished one worked at low-pressure. What folly is it, then, while finishing the engine, so to damage the boiler that it will not generate steam! Once more, the system is a mistake, as involving a false estimate of welfare in life.
If now the motors were made to run dynamos conveying low-pressure currents to the public, there is no possible way whereby this high-pressure current could get to the public."
How men existed or did any business at all before the advent of the "ticker" is a wonder. But the Chamber, the creator of low-pressure and high-pressure, the inspirer of the "ticker," is the great generator of business. Here I found Henderson in the morning hour, and he came up to me on the call of a messenger. He approached, nonchalant and smiling as usual.
He held that the heat and phosphorescence produced in a low-pressure tube were caused by streams of particles, projected from the cathode with great velocity, striking the sides of the glass tube. The composition of the glass seemed to enter into this phosphorescence also, for while lead glass produced blue phosphorescence, soda glass produced a yellowish green.
They fell into the great aperture. Jeter and Eyer flung themselves flat. But the bombs had worked sufficient havoc. They had removed all protection from the low-pressure stratosphere. The air inside the space ship went out with a rush.
'As general items of river history, we quote the following marginal notes from his general log 'In March, 1825, Gen. Lafayette left New Orleans for St. Louis on the low-pressure steamer "Natchez." 'In January, 1828, twenty-one steamers left the New Orleans wharf to celebrate the occasion of Gen. Jackson's visit to that city.
To successfully steam a vessel up those streams against the remarkably swift currents, high-pressure engines had to be adopted generally. In that year, however, there were still a number of boats on the Mississippi and Ohio which, like the Champion, had low-pressure engines and the grotesque walking-beams.
After a while, though, other steamboats operating low-pressure engines copied the idea, and there were several "walking-beam boys" employed on the rivers, and their flags were remodeled to have some distinctive feature each. It was a perilous situation to be employed in, but I am unable to find the record of any "walking-beam boy" being killed or injured in the machinery.
Elimination of causes of trouble with the low-pressure balance piston not only makes it possible to reduce the diameter of the cylinder, and prevent distortion, but enables the entire spindle to be run with sufficiently small clearance to obviate any excessive leakage of steam.

While their columns are dancing up and down with laughter at this somewhat tepid and low-pressure pleasantry, there come in a New York Reaumur and a Centigrade from Chicago. The Fahrenheit, which has got warmed up to temperate, rises to summer heat, and even a little above it. They enjoy each other's company mightily.
