But this self-acting machinery follows not the soldier through his campaigns.

3 is a self-acting, simple open range in modern use, and may be had of two qualities, ranging, according to their dimensions, from £3. 10s.

Mr. Leone Levi has calculated that to make by hand all the yarn spun in England in one year by the use of the self-acting mule, would take 100,000,000 men.

In wagon boilers this is generally accomplished by self-acting mechanism.

In this contrivance the fire is replenished with coals by a self-acting mechanism.

Q.Have any other plans been devised for feeding the fire by self-acting means besides that of a revolving grate? A.Yes, many plans, but none of them, perhaps, are free from an objectionable complication.

It is very doubtful whether any of these contrivances satisfy all the conditions required in a plan for feeding furnaces of the ordinary form by self-acting means, but the problem of providing a suitable contrivance, does not seem difficult of accomplishment, and will no doubt be effected under adequate temptation.

A.The whole of the plates of a boiler should have the holes for the rivets punched, and the edges cut straight, by means of self-acting machinery, in which a travelling table carries forward the plate with an equal progression every stroke of the punch or shears; and machinery of this kind is now extensively employed.

Q.What is the amount of power necessary to drive cotton mills? A.An indicator or actual horse power will drive 305 hand mule spindles, with proportion of preparing machinery for the same; or 230 self-acting mule spindles with preparation; or 104 throstle spindles with preparation; or 10-1/2 power looms with common sizing.

The self-acting mules are Robert's, about one half spinning 36's weft, and spindles revolving 4800 turns per minute; and

From the first it followed that the substances were self-acting forces; from the second, that they were immaterial units.

Self-dependent, self-acting, and self-taught, it is apprehended that few men, with so little means and few advantages, have been in so peculiar a sense the architect of their own fortunes.

We will begin with the last in our series, both because we think it the newest and the most ingenious part of Mr. Darwin's whole argument, and also because, whilst we absolutely deny the mode in which he seeks to apply the existence of the power to help him in his argument, yet we think that he throws great and very interesting light upon the fact that such self-acting power does actively and continuously work in all creation around us.

There are 126 looms in operation, all self-acting and each one making 47 bags daily; the bags are a little more than three and a half feet long, and chiefly used, I believe, for flour and grain.

And this is the very kind of sacrifice which must be anticipated by those who so misunderstand the doctrine of evolution as to believe that the world is improved by some mystic and self-acting social discipline, which dispenses with the necessity of pertinacious attack upon institutions that have outlived their time, and interests that have lost their justification.

If there is any risk of the instrument getting broken from fall of materials or other causes, it may be fitted with an ingenious self-acting apparatus shutting off the supply.

We will also pass them, and illustrate some of the SELF-ACTING WATER-RAISING DEVICES.

He has lost three of his fingers, through incautiously handling a self-acting rat-trap of his own construction; and had his left eye blown out, while investigating the exact interval between combustion and explosion.

He had expected that it would save him from a great deal of social intercourse of a frivolous kindthat it would offend the fools, but not the sensible people; and so would serve as a self-acting test by which those worth knowing would be separated from those not worth knowing.

perhaps there lay the domestic difficulty of which Julius could not speak; yet, as if answering the thought, Dr. Easterby said, "After all, charity is the true self-acting balance to many a sweet untaught nature.
