Utah Station. — Dynamoineter tests of the draft of sleighs and sleds have been 

 completed. It was found that under average conditions of sleighing the draft of the 

 sleigh was greater than that of the wagon on bare roads. The draft was less when 

 the load was placed on the front end of the sled than when placed on the rear end, 

 which is the reverse of what was found to be true of the wagon. The angle of draft 

 or the point of attachment to the sled made no diiference in the draft.
