They even prohibit maintenance of prices at production cost levels. The result is a dislocation of employment and wages and a serious undermining of consumer pur chasing power. While it is becoming apparent that the public will demand protection from these evils, the operations of legislative machinery are so slow that early statutory relief is unlikely. Meanwhile no effort should be spared to educate industry to the necessity of voluntary self-regula tion. Reason dictates, says Mr. Charls, that per sonal selfishness shall give way to a sense of duty to competitors and to society at large the United States the only autl trade associations and institutes n the authority of reason The law prohibits manufacturers from as ng among themselves to limit the squandering ion’s wealth in creating over-capacity; it prohi igreements to regulate reasonab! » the known demand; it condemns any agreement maintain a price level even at production cost. 7 hw . rihit?i ] : } “17 these three prohibitions alone it obstructs the tabilization of employment and wages, and, by the » token, constantly undermines consumer pu! ng power.

[RON 11 X-ra The Trend in Refinery Plants S in many other fields, the trend in the design of pressure cracking apparatus is toward higher pressures and temperatures and larger units A modern cracking unit such as that now nearing completion at Bayonne, N. J., has a capacity equal to about 20 of the old stills which were in high favor not more than eight or ten years ago. This new unit, which will be capable of handling a charge of between 8000 and 9000 bbl. a day, will require more than 1500 tons of steel in its con struction. Because of the high temperatures and pressures at which the plant operates the finest materials and workmanship have entered into the building of the various tanks and towers It is a compliment to the steel industry and the steel fabricating art that solid forged and welded vessels such as required in this unit can be made Welded jcints, 100 per cent tested, heat-treated fire box steel shells and forged alloy fittings are some of the features. A further trend in modern cracking unit design is toward more and more utomatic operation. All the instruments and con trols are brought to one location in the present jesign, and the temperatures, rate of flow and ther variables are governed automatically But four men are needed in the operation of the entire init in contrast with perhaps 25 for operating the ne capacity in the old type of still The Iron Age.
