 JfS, pp. 16). — An account is given of two tests (August 17 and October 

 3, 1899) on wet and dry sandy roads of the draft, as measured with the 

 dynamometer, of wagons with metal wheels of standard height having 

 tires 6 in. and 1^ in. wide. The load in each case was 2,000 lbs., the 

 length of run 200 ft. The results were as follows: 



" In all conditions of sand roads the draft of the broad tire Avas from 7.49 to 28.6 

 per cent less than that of the narrow tire. 



"There was little difference in the draft of the l)road tire on wet or dry sand. 

 The narrow tire pulls a little more than 5 percent lighter in wet sand. 



"The condition of the road was not improved by the use of the broad tire except 

 for Ijroad tires.
