 100 ft. mark. Going back to the start there is now to be recorded the 

 consecutive measurements of the four feet. By means of an ordinary 

 small blank book ruled as in Fig. 34, these measurements can be put 

 down quickly as we go along the line and take readings at the point of

 mal computations are more readily made and therefore their use recom-

 in this country it would simplify matters vastly by ridding calculations 

 of their complex figuring. So likewise here, if we were to figure all
