Gradiiii' and Levelling, 



3^5 



scraper is shown in the illustration. The 7-feet size, however, with a 

 four-horse team, is recommended for general use as being hand\ in its 

 capacity and more easily worked. This type, somewhat more elaborate 

 than those figured for the other sizes, gives good satisfaction and has, bv 

 long experience, had its design perfected to ride smoothly when full and 

 to balance well when empty. Consequently special attention when making 

 should be paid to the dimensions figured.
