These are, briefly, plain sewing machines; sewing machines as used in factories, where they are moved by steam power; and special sewing machines, embracing many interesting forms, only recently introduced. We have thus to consider, in the first place, the general efficiency of the machine as a plain stitcher.

The concrete material may be so complex that again the essential point is lost in the mass of detail. No perspective can be obtained because of the complexity witness work with principles of machines in physics and the circulation of the blood in biology. Sometimes the diagram or word explanation with nothing of the more concrete material is the best type of illustration.

The tissues woven in gold, the gold and silk embroideries and Cashmere shawls, are of the highest degree of perfection. The dexterity of the workmen appears still more surprising after seeing the simple machines which they employ to produce their beautiful wares. It is extremely interesting to walk about the principal streets of Delhi in the evening.

Such smoothers were at one time favoured in the kitchen laundry in the days when servant-maids excelled in getting up linen, and prided themselves on the beautiful gloss they were able to impart in the days before public laundries with their modern glossing machines were instituted.

Our process for reducing gases into fluids is of admirable simplicity. A simple bent tube, or a reduction of temperature by artificial means, have superseded the powerful compressing machines of the early experimenters.

"Darwin among the Machines," a letter signed "Cellarius" written by Butler, appeared in the Press. Sold out his sheep run and returned to England in company with Charles Paine Pauli, whose acquaintance he had made in the colony.

The machines for combing and carding, of the most improved make, will work wool of one and a half inch in the staple, while for the old process of hand- combing four inches was the minimum. But we must not enter further into these details, as it is our purpose rather to indicate the interest and importance of certain manufactures than to describe the process minutely.

How the War advanced design may be judged by comparison of the military requirements given for the British Military Trials of 1912, with performances of 1916 and 1917, when the speed of the faster machines had increased to over 150 miles an hour and Allied machines engaged enemy aircraft at heights ranging up to 22,000 feet.

The soft hands of women reached out of the masses of people about him, out of the old dwellers and new dwellers in the city that was growing up about the factories where his machines were being made in ever increasing numbers. New houses were constantly being built along Turner's Pike that led down to his workshop at Pickleville.
