on the market, and especially that produced by gasworks, has a n injurious effect upon the engine, owing largely to the presence in it of sulfuric acid. One of the leading motor car manufacturing firms has taken the pains to investigate the effects of poor quality benzol upon lubricating oil and has found that when sulfuric acid is present in the benzol a semi-solid deposit is formed in the crank case, due to the leakage of benzol past the pistons. This deposit consists of carbon and sulfuric acid and the acid rusts the valves and stems. The best remedies for this state of things are more thorough washing of the spiiit or, failing this, the mixing of the benzol with petrol in the proportion of 65 per cent benzol and 35 per cent petrol, the alkaline ingredients in the latter neutralizing the acid content of the benzol. Everything, however, points to alcohol as the fuel of the future. The thermal value of alcohol is only about one-half that of petrol or benzol, but whereas it is not advisable to use a higher compression pressure with the last-mentioned fue!s than about 80 lbs. per sq. in., with alcohol the compression may be raised to a pressure of zoo lbs. without fear of preignition, and the quantity of air required t o complete combustion is little more than one-half. Last year the Royal Automobile Club appointed a committee t o investigate and report on alcohol as a fuel. The report has not yet been published, but the most important problem which this body will have t o investigate is that of finding a suitable denaturant which will satisfy the excise authorities. If the efforts of this committee result in the abatement of the duty and some modification of existing restrictions on the manufacture of alcohol, capital will no doubt be readily found to provide factories for the production of the fuel in such quantities as will, a t any rate, serve t o prevent the further rise in price of petrol on which so much of the nation's welfare depends.--4.

IRON PRODUCTION OF THE U. S.-MAY, I915 The total pig-iron output of the United States in May was 2,263,470 tons, or 73,OIj tons a day, against 2,116,494 tons in April, or 70,jjO tons a day. With 2 0 j furnaces in blast June rst, or ten more than on May Ist, the active capacity was 74,343 tons, against 71,385 tons one month previous. Pig-iron production is now a t the rate of 27,400,ooo tons a year. On April 1st it w-as a t 26,000,000 tons, and on January 1st a t 18,000,boo tons a year.

TAR DEHYbRATION AND TOLUOL RECOVERY The question of the dehydration of tar has lately attracted considerable attention in England, since prepared tar is being generally adopted for road construction and the light oils driven off in the process of dehydration contain all the toluol and phenol originally in the tar, products now in urgent demand for the manufacture of explosives. One ton of average crude gas-works tar yields, when dehydrated, 160 gallons of prepared tar, 30 gallons of light oils, and I O gallons of ammoniacal liquor. An average sample of zoo cc. of the such light oil, washed with caustic soda, gave 18 per cent of tar acids; on fractionating the washed oil, the following results were obtained: Temp. Per cent product Benzol Up t o 100" C. 35 100O t o 120' C. 1 0 . 5 Toluol

Temp. Per cent product Solvent naphtha 120' t o 125O C. 28 Residue 40.5 Creosote

The oil also contained 6 per cent of very good pyridine. The quantities of fuel required per ton of tar distilled are with plants actually a t work, 67 lbs. of breeze or 450 cu. ft. of gas of goo B, T.U. [ J . Gas Lighting, 130 (1915), 3301.
