That's the substance of the leading article in the September Technical World, with reference to handling the Mexican peon on the fruit ranches of California. The owner found that the enterprise did not seem to go as it should. Contrary to all precedent, he permitted a new policy to be established—that of treating the peon just as if he were the self-respecting, independent individual that every man ought to be. What the result was the reader will find out for himself by reading this thoroughly absorbing article. Walter V. Woehlke is the author.

AVIATORS' ECSTASY A startling new theory has been advanced as to the cause of so many aeronautic disasters. We all have heard of persons who, when on a high building, feel an almost irresistible impulse to leap out. Aviators, it is alleged, sometimes become so intoxicated by the ecstacy of the feeling that they are suspended in space that, for a moment, they forget all sense of danger, and, losing control of the machine, come to their senses only to find they are plunging helplessly earthward.

TENANTS THAT BUILD The average farm tenant has been declared by some a curse to the land. Now a new sort of tenant has appeared, who, leasing land for a fairly prolonged period, at the expiration of his lease leaves the land in such excellent condition that he could not induce the landlord to renew the tenure scarcely under any circumstances. This unique condition of affairs is entertainingly discussed by Forrest Crissey.


MILLIONS It was recently stated, on excellent engineering authority, that such cities as Chicago, New York and Philadelphia waste from forty to seventy per cent of the total water supply actually pumped. This means that such gigantic enterprises as the Ashokan dam recently constructed to enable New York to replenish its waning water supply would probably be unnecessary if care were taken in properly conserving the supply already at hand.

These are but four of the twenty big articles that will appear in the September number of the Technical World Magazine. In addition, it will be chock full of the briefer illustrated items that have proved so popular. This will be one of the strongest and best numbers ever issued.
