lowed to escape through the valve and the temperature may be

These boots are 6. 8 and 10 inches in diameter and range in 

 lieight from 10 to 30 inches. They are made of heavy canvas 

 with an increasing number of i)hes toward the bottom, to above 

 the top of the hoof, and have an inside lining and an outside cov- 

 erine of rubber. In addition iliere is a removable reinforcing 

 bottom which protects the boot in case it should be necessary to 

 soak the foot without removing the shoe. Canvas and rubber 

 straps are used as fastenings, the strap on the three larger size- 

 passing over the animal's back, while the small-sized boot fasten- 

 above the fetlock. |\'oorhees Kubber .Manufacturing Co., Jersex

AtJTOMOBILE STEERING WHZEL. 



.An improvement on the ordinary steering wheel for automo- 

 biles is one made of Condensite, a product which comes 

 very close to being 

 synthetic hard rub- 

 ber. The edges are 

 notched, which pre- 

 vents the hands of 

 the driver from slip- 

 The wheel is 

 jet black and finely 

 polished similar to 

 that of hard rubber, 

 and . the manufac- 

 turers claim that it 

 retains this appear- 

 ance ; also, that it is 

 very elastic, and will 

 not crack on the spider. [Essex Rubber Co.. Inc., Trenton, Xew

RUBBER BOOTS WITH MUFELER TOP. 



The novel feature in this child's rub- 

 ber boot — pleasingly named the "Red 

 Bird" — is the muffler top, made of knit- 

 ted red wool and as cosy and comfort- 

 able in feeling as it is in looks. When 

 playing out in the snow or wet, rubber 

 boots are the best protection a child 

 can have. But cold winds can enter at 

 the top, and — if youthful enthusiasm 

 reaches a high enough pitch — even snow, 

 or the aftermath of a particularly en- 

 joyable splash in a puddle. The woolen 

 mutiler top is therefore a very practical 

 innovation for that friend of children's 

 playhours, the ever-useful rub- 

 ber boot. fCanadian Consoli-

that combines the tiexibility

to sustain the weight of a heavy man. The l>ar is made ol se- 

 lected hickory, and has steel tubular ends into which the iron 

 sockets holding the rubber cushions screw. It is used for chin- 

 ning exercises and also for abdominal work, being adjustable 

 to any height. [A. G. Spalding & Bros., Xew York.] 



Another indoor apparatus for athletic exercise, in which rub- 

 ber is used, is a vaulting pole of bamboo, would at short inter-

.\ new hose, that combines the llexibdity ol rubber hose and 

 the resistibility to pressure of the all-metal hose, has lately 

 appeared on the market, and is of interest to steam users. 



It is built as follows: The 



metal inner tube is of spe- 

 cial ball-bearing construc- 

 tion, overlaid with a mag- 

 nesia composition, around 

 which is spun a woven insu- 

 lated fabric, covered by a 

 coating of rubber with a 

 woven jute covering for 

 protection. 



The metal tube carries the 

 pressure, while the magnesia 

 is to prevent heat conduc- 

 tion, and the next layer is 

 for insulation. The woven 

 fabric prevents kinking of 

 the hose by being woven to 

 the maximum bend that 

 the hose will describe — the 

 smallest circle that may 

 be permitted without strain.

RUBBER MAT FOR REVOLVING DOOR. 



This rubber mat is specially designed for use with revolving 

 doors, and can be obtained in any size by giving the diameter 

 of the circle required, the 

 size of the center post on 

 which the door revolves, 

 and the distance from the 

 center post to front and 

 back. It is made in four 

 sections. The front and 

 back sections are perfo- 

 rated, and the two side 

 sections are made of solid 

 rubber, which gives addi- 

 tional weight to the mat 

 and insures an absolutely 

 safe foothold when pass- 

 ing through the door.

ALL-RUBBER SIPHON. 



In transferring liquid from a cask with a piece of hose or 

 tubing, the air must first be expelled before the flow commences. 

 The old method of starting the flow by inserting the hose in the 

 liquid and sucking on the other end is of course a very un- 

 sanitarv one. The labor, the waste of material, and, most im- 



portant of all, the lack of hygiene in this method can readily be 

 seen. .AH these undesirable factors are eliminated by a modern 

 device called the "Queen City Siphon," in which a rubber bulb 

 at the end of the tuiie performs the neces.sary service. Two 

 compressions of this bulb will start the flow, which can be in-
