arranging land for triangular planting, say the trees arc to 

 be 20ft. apart, the spaces in the first row (A to F), the 3rd, 

 5th, 7th, and so on, will be 20ft. apart. The 2nd (B to C), 

 4th, and other rows, where the trees come between two 

 trees in the 1st and 3rd, will, by measurement on the side 

 lines, be 17ft. 4in. The triangular slope (as between A and 

 B) makes up the difference, so that when the trees are 

 planted they will be 20ft. apart from each other, in which- 



ever way they may be measured. The side-line measure- 

 ments, for various distances apart, from 10 to 20ft. are :
