Bring DE, at E end, to a point on leg AB, where the 

 spirit level indicates level; then mark or put a hole 

 through both for bolt to work in. This hole on AB leg we 

 call zero, which means level. Now we wish to make a 

 scale that will enable us to run a terrace having a fall 

 anywhere from an inch to four inches. Let some one raise 

 the foot of AB one inch and lower crossbar DE until level; 

 then put a hole through AB leg, and call this hole No. 1. 

 Now raise foot of AB two inches and put another hole in 

 AB leg and call it No. 2, and so on until we make our scale 

 to four or five inches. The half-inch is then gotten by di- 

 viding the distance between holes and numbering halves. 

 Now we have an instrument made that should not cost

 handled, suffice for most of this kind of work. 



"In terracing a field start about three 'feet from the top 

 of the hill, and begin to lay off the first terrace. Usually 

 about one or two inches fall to the rod ^jill be sufficient. 

 Try to put the second terrace so that it will be about three 

 to four feet lower than the first, and so on down the hill 

 until the whole field is terraced. Now, if a field has a 

 swag about the center and water collects from both direc- 

 tions in this swag, to avoid this begin the terrace in the 

 swag and go both ways, providing there is a good outlet 

 at each end. Lay off the terrace, giving one to two inches 

 fall, as desired, by fastening the cross-bar DE at E in the 

 hole giving the fall desired. Start at the point we have 

 selected to begin, and let the short leg, or the leg with the
