To Prevent a Colt from Becoming 

 Tangled in a Halter Rope 



IN the illustration a device is shown that 

 will prevent a colt from becoming 

 tangled in the tie-rope of the halter. The 



Popular Science Monthly 



The weight keeps the tie-rope taut all the 

 time and the spring cushions the jerks 



old method of a weight is used, but a spring 

 is applied to cushion the jerk a colt will 

 give when first tied with a halter. The 

 weight consists of a piece of hardwood 

 43^ in. long and 3^ in- in diameter. A 

 2-in. hole is bored in one end of the wood 

 4 in. deep, and a i-in. hole bored through 

 the center of the remaining 3^ in. of the 

 wood. This makes a seat for the coil- 

 spring A to B. The spring should be 

 8 in. long, of the open variety and made of 

 wire about 3/16 in. in diameter. The tie- 

 rope is passed through the spring and 

 secured by a knot at the bottom of the 

 block as shown. The hole in the manger 

 should be about i}4 m - i n diameter to 

 take the tie-rope loosely. This will effec- 

 tually prevent the spring from passing 

 through. — J. O. McDonnell. 



Effects of Oil and Grease on 

 Rubber Tires 



IT is pretty generally known that gasoline, 

 grease, oil and other fatty substances are 

 solvents of rubber. 



If garage floors are not kept clean and 

 tires stand in a pool of oil, the treads 

 soften and the traction strains in service 

 stretch the rubber in a wavy outline, 

 eventually causing it to separate from the 

 fabric body underneath. 



Probably the most damage is experienced 

 from grease, in the differential housing, 

 working out into the brake drums and then 

 on to the side walls of the tires. This may 

 result from loose bearings, too much grease 

 or from using grease not suitable for 

 differential. 



Grease and oil may be very easily 

 removed by using a rag saturated in 

 gasoline. Gasoline, although a solvent, 

 evaporates quickly, and, if applied in small 

 quantities, will not cause any injury when 

 used as a cleaning agent. 



Ordinary injuries to the rubber cover do 

 not prevent successful repairs but not often 

 can work be well done when materials have 

 been affected by oil or grease. Invariably 

 blistering during vulcanization results. 



An Irish Thrush Rings for 

 His Food 



FOR a token of remembrance of a trip 

 abroad a lady promised a friend that 

 she would bring back a bird of some kind. 

 An Irish thrush was selected. When caged 

 the bird cultivated the habit of pounding 

 the metal bottom of his inclosure with a 

 small gong top, taking hold of the edge 

 with his bill and manipulating it just as a 



Thrush rings bells to 

 attract attention when 

 food cup is empty 



\ SMALL GONG USED FOR AMUSEMENT 

 AND EXERCISE 



Calling for food by ringing a string of sleigh- 

 bells which have been hung from the cage top 



workman does a pick. When his mistress 

 fails to keep his food cup filled he jingles a 

 string of sleigh-bells that are fastened to 

 the cage top.
