chlorine gas a current of 100 amperes at 

 about 12 volts. 



After the treatment the pile was left in 

 the bay for twenty-four hours, in order that 

 should there be any power of revival it 

 might manifest itself ; then it was cut open, 

 and all Xylotrya were found to be dead. 

 The result" was accomplished principally by 

 the corrosive action of the chlorine upon the 

 exposed parts of the Xylotrya, that is, the 

 so-called "tail," which in reality constitutes 

 both their feeding and breathing organs. 

 It appeared that all exposed tails in the pile 

 thus treated turned white, while when the 

 animal is alive, they are a dark gray. As 

 the chlorine penetrated the borer it coagu- 

 lated the albumen which constitutes part of 

 the body, and which shows itself in white 

 spots. The original appearance of the Xy- 

 lotrya when alive is almost transparent and 

 glassy. 



A TIMBER FAMINE PREDICTED 

 IN TWENTY YEARS , 



GIFFORD PINCHOT, the ex-govern- 

 ment forester, made the declaration, 

 on the return from a six months' in- 

 spection trip, that "in twenty years the tim- 

 ber supply in the United States on gov- 

 ernment reserves and private holdings, at 

 the present rate of cutting, will be ex- 

 hausted, although it is possible that the 

 growth of that period might extend the 

 arrival of the famine another five years." 

 Mr. Pinchot urges that the magnitude of 

 the danger should not be underestimated, 

 for every- man, woman and child in the 

 country would be affected by such a fam- 

 ine. Although about one-fifth of the forest 

 area of the country is made up of gov- 

 ernment reserv'es, attention is called to the 

 fact that the government does not control 

 a corresponding fraction of the timber sup- 

 ply, because the government lands are not 

 so good as those owned by private own- 

 ers. Money is to be asked for to extend 

 the forestry service, and to push the work 

 of reforesting the denuded timber lands, 

 although it is claimed to be utterly beyond 

 the powers of the service to meet the sit- 

 uation and prevent serious trouble. An ef- 

 fort will be made to protect the Appalach- 

 ian forest and promote the growth there. 



The State forester of California has ad- 

 vocated a plan that is being watched with 

 much interest. In that State, under the 

 police power, the forester is attempting to 

 protect the watersheds and to prevent pri- 

 vate owners from devastating these lands in 

 a manner that will injure the irrigation of 

 lands lying below. Figures have been pro- 

 duced to show that at the present increase 

 in the value of timber land, the owners of 

 such property are making more by letting 

 the timber develop than they would by cut- 

 ting and placing the money out at inter- 

 est. 



GRINDING CEMENT 



FINENESS of grain is greatly to be 

 desired, both in finished cement anrl 

 in the raw materials of which it is 

 made. In the new Pfeiffer cement ma- 

 chine the process of grinding is kept sep- 

 arate from the expulsion of the meal, or 

 product of grinding. The last-named oper- 

 ation is effected by means of a fanning mill 

 of peculiar construction which, without em- 

 ploying any sieves, delivers a product of 

 very fine grain. The machine requires 

 much less power than the ordinary ma- 

 chine, so that a very fine cement can be 

 produced more cheaply than common ce- 

 ment is produced by the usual methods.

"Quilt" 



A "Comforter" that Will Keep the Whole 

 Family Warm 



A house lined with Cabot's Sheathing 

 Quilt will be wind and frost proof. It will 

 be warm in winter and cool in summer. No 

 heat can get out nor cold get in, or vice versa. 

 It is not a mere paper or felt, but a thick 

 matting which retains the warmth as a bird's 

 plumage does. ''It is cheaper to build inarm 

 houses than to heat cold ones.'' 



Sample and catalogue free on request.

/ Save Your Garbage Troubles 



Ever wished for a garbage can in 

 which garbage cannot ireeze in 

 winter — and stink in summer? 



A can in which flies cannot breed and then 

 spread typhoid germs? A can having a 

 cover which every time closes tight auto- 

 matically — and cannot be opened by prowling dogs 

 and cats? A can, which being out of sight, does 

 not disfigure the backyard? A can which is practi- 

 cally indestructible? The StephensonUnderground 

 Garbage Receiver has all these advantages. 



My receivers are SOIiD DIRECT. 



For the satisfaction of yourself, your husband, your maid and your 

 garbage man you should at least send for fully illustrated de- 

 scriptions of my Underground Garbage Receivers and names and addresses of hundreds of pleased u«er«
