which it is to do. Ordinarily both the first cost and the cost of opera- 
tion of a small track will be less than of a large one. but often the 
small track will not cany as large loads as is desired, and more trips 
to haul a given amount of material will therefore be necessary than 
with a larger track. A track which is too large, however, would 
have to be operated with only a partial load a great part of the time, 
and the extra cost would more than offset the advantage of being 
able to carry larger loads on. exceptional occasions.
