98 The Use of a Triangle. 
Three persons must now carry the triangle, beginning on one side of 
the field, say eight feet from the fence, and guided the first time through by 
a line of stakes. Carry the triangle with its side to the line of guide stakes 
and its point in. The head man and the inside man will stick pins, while 
the rear man will slip his corner each time upon the pin set by the head man. 
After the first time across, the man at the inside point of the triangle 
alone will set pins, while the other two fit their corners upon the pins in 
the last row set. Thus one row of pins only is set each time you go across 
the field.

One Corner of Triangle—All Being Made Alike. 
MBs If the triangle is exact, and the first row of pins is set perfectly straits 
and the pins are always set perpendicularly, everything will now work like 
a charm and the job will be perfect; and it is so simple and easy that a man 
and two small boys can lay off from five to ten acres in one day. Remem- 
ber that no guide stakes are used anywhere after the first time through. 
The Triangle on Hillside—The use of the triangle requires 
a little nicety in “leveling up’ where the piece is hilly. By 
using a plumb-line at two corners of the triangle, the third cor- 
ner resting on one of the stakes, leveling the triangle and bring- 
ing one of the plumb-lines over another stake already set, the 
position of the other line would determine the position of the 
next stake. This method has worked fairly well, even in places 
where the slope was sufficient to give a fall of six feet between 
the trees, which were set twenty feet apart. 
Locating in Triangles with a Chain.—Instead of a wooden 
triangle, a chain has been used in this way :— 
First stretch a chain along one side of the ground, setting by it the first 
row of stakes. This forms the base line. Have a piece of chain just twice 
the length of the established distance between trees, with ample rings on 
the ends and a joint in the middle. Put one of the rings over the first 
stake and the other over the second stake. Then take the joint in the
