Halaman 131 - I advanced toward the second turning, by a fly from the railway. I made a sign to the driver to stop. As he obeyed me, a respectable-looking man put his head out of the window to see what was the matter. "I beg your pardon," I said; "but am I right in supposing that you are going to Black water Park?
Halaman 413 - I refer to is his reckless statements, without any ground of truth. You have seen instances of this in his speech to you. Now, the reason of this lies in the constitution of his mind. The moment he begins to talk all his mental operations cease, and he is not responsible.

Service Application. — In applying the brakes to steady the train upon descending grades, or for reducing the speed for any purpose, be very careful not to make too great a reduction of pressure in the outset, as the speed of the train will be too quickly or too much checked, and it will be necessary to release the brakes and apply them again later, perhaps repeating the operation. Apply the brakes lightly at a sufficient distance...
Halaman 128 - I ascertained the proportion between the weight of the experimental carriage and the coal waggons at that point when the wheels of the carriage would surge or turn round without advancing it. The weight of the carriage and the number of waggons also were repeatedly varied, but with the same relative result. This experiment, which was on a large scale, was decisive of the fact, that the friction of the wheels of an engine carriage upon the rails was sufficient to enable it to draw a train of loaded...
Halaman 449 - Plate 20, are enlarged sections of the valve itself, the first in the normal condition when it is closed, and the second when it is opened to reduce the pressure. In order to understand the action of the valve, suppose that four blocks act against a pair of wheels, the load at A (Fig.
