REMARKABLE TIRE RECORD. 



The record run, 5 days 18 hours and 22 minutes, recently made 

 from New York to San Francisco by S. B. Stevens, under the 

 au.«pices of the American Defence Society, to try out the pos- 

 sibilities of the automobile in time of war, was accomplished 

 on Silvertown tires. The distance between New York and 

 Omaha, 1,485 miles, was made in 48 houis without tire trouble. 

 The same set of tires were used as far as Cheyenne, about 

 450 miles farther, where they were changed as a matter of pre- 

 caution. According to Mr. Stevens, they exhibited but little 

 signs of wear on his arrival at San Francisco. 



In the manufacture of garters in Great Britain, the webbings 

 and threads are made there, but practically all of the metal clip 

 ends are imported from the United States. Previous to the 

 war many French garters were imported into England, but that 

 trade has now almost entirely ceased.
