Both the oil for lubricating the bearings and the water for cooling the cylinders were circulated by pumps, and all parts of the valve gear, etc., were completely enclosed for protection from dust.
Somewhere hard by, a bonfire was pungently smouldering; there was a sour smell where a flock of geese had been feeding all day; flaring acridly across was a transitory reek of burnt lubricating oil, and the hint of a cigar so faint that it was gone before he could be sure of it. . . . The lumbering creak of the mill-wheel rose assertively above the drone and plash of the stream; a shiver of rain and a gentle sigh of wind in the top branches of the trees behind him were suddenly swallowed by the hoot of an owl.
When the water is used over and over again a considerable proportion of the fatty acids of the oils used for lubricating the piston is carried over with the steam and is found in the condensed water which is introduced into the boiler along with the water. Here it commences action, which proves quite as injurious to the boiler as it does to the cylinder, but in a different way.
An instant later, he was diving to the right, breaking his fall with the butt of his auto-carbine, rolling rapidly toward the cover of a rock, and as he did so, the thinking part of his mind recognized what was wrong. The tank-tracks had ended against the vine-grown side of the ravine, what he had smelled had been lubricating oil and petrol, and the leaves on some of the vines hung upside down.
Brutus and Cassius stretched themselves on the rug to digest mushrooms and made gravies in the lubricating heat of the fire. "For what we have received, the Lord make us truly thankful," said the admiral. "Go downstairs, my good girl, and get your supper. A light meal, Lucy, if you take my advice a light meal, or you will have the nightmare.
After having examined the symptoms, he declared that the patient had been poisoned with arsenic, and prescribed only draughts and lubricating injections, to defend the coats of the stomach and intestines from the vellicating particles of that pernicious mineral; at the same time hinting, with a look of infinite sagacity, that it was not difficult to divine the whole mystery.
*Glands.*—As generally understood, glands are organs that prepare special liquids in the body and pour them out upon free surfaces. These liquids, known as secretions, are used for protecting exposed parts, lubricating surfaces that rub against each other, digesting food, and for other purposes.
The burning fire of wood, coal, or gas; the preparation of food to excite and to satisfy the appetite; the change of minerals into the iron, steel, copper, brass, lead, tin, lighting burning and lubricating oils, dye-stuffs and drugs of commerce; the change of the skins, wool, and hair of animals, and of the seeds and fibres of plants, into clothing for human beings; the manufacture from rags, grass, or wood of a material fitted to receive and to preserve the symbols of human hopes, fears, aspirations, love and hate, pity and aversion; the strange and most delicate processes which, happening without cessation, in plants and animals and men, maintain that balanced equilibrium which we call life; and, when the silver cord is being loosed and the bowl broken at the cistern, the awful changes which herald the approach of death; not only the growing grass in midsummer meadows, not only the coming of autumn "in dyed garments, travelling in the glory of his apparel," but also the opening buds, the pleasant scents, the tender colours which stir our hearts in "the spring time, the only pretty ring time, when birds do sing, ding-a dong-ding": these, and a thousand other changes have all their aspects which it is the business of the chemist to investigate.
If the machinery of the Law could be depended on to fathom every case of suspicion, and to conduct every process of inquiry, with moderate assistance only from the lubricating influences of oil of gold, the events which fill these pages might have claimed their share of the public attention in a Court of Justice.
Remove the standards, drill and tap the bed-plate holes, and replace parts as before, taking care that the lubricating holes in the bearings point vertically upwards. Then solder bearings to standards. If any difficulty is experienced in getting all four standards to bed properly, make the bearing holes in the two inner ones a rather easy fit.
