Page 59 - The earth round the place, for above two miles, has this surprising property, that by taking up two or three inches of the surface, and applying a live coal, the part which is so uncovered immediately takes fire, almost before the coal touches the earth ; the flame makes the soil hot, but does not consume it, nor affect what is near it with any degree of heat.
Page 59 - When the weather is thick and hazy, the springs boil up the higher, and the naphtha often takes fire on the surface of the earth, and runs in a flame into the sea in great quantities, to a distance almost incredible.

Page 28 - This method of transmitting power depends upon two principles in mechanics: (1) The dynamic force is measured by the product of the force and the velocity with which it moves ; (2) In mechanical work, power may be exchanged for velocity, and velocity for power. To illustrate, let us suppose a bar of iron, having a cross sectional area of one square inch, to move endlong at the rate of two feet per second. Now, if the resistance overcome is say 5,000 pounds, work will be performed at the rate of 10,000...

Page 25 - The Sawyer spindle was limited in speed. With an unbalanced load it would vibrate and gyrate, at more than 7,500 turns per minute, so as to become useless. The Rabbeth spindle, on the contrary, will bear any speed desired, and the limit of production of the frame is transferred from the speed that the spindles will bear to the speed with which operatives can make good piecings of yarn broken in the o|)eration of spinning.
