CALIFORNIA FRUITS: HOW TO GROW THEM 



After the field is staked, each alternate stake in the cheek rows should be 

 removed. The following table will show the number of trees to the acre by 

 the square and septuple system : 



Square Septuple 



10 feet apart 435 500 



12 feet apart 302 347 



14 feet apart 222 255 



16 feet apart 170 L95 



18 feet apart 134 ir,-i 



20 feet apart 109 125 



21 feet apart 99 114 



22 feet apart 90 103 



24 feet apart 75 86 



For any distance not given in the above table, calculate the number of 

 trees to the acre by the square system, and add fifteen per cent. This will 

 give the number if planted septuple. 



Laying Out Hexagonals with a Triangle. It is possible to lay 

 out an orchard in hexagonal form by working from stake to stake 

 with an equilateral triangle of dimensions equaling the distance 

 required between the trees. 



One corner of triangle all being made alike. 



Take three strips of one-by-two-inch dry pine or redwood, and as long 

 as you wish the distance between the trees. Cut the strips the same length, 

 and fasten the corners of the triangle firmly together by nailing two pieces of 

 pine board six by six inches. 



If the long strips are set up edgewise, the triangle will be much stiffer 

 and better to carry. Through the corner boards bore an inch hole, making 

 sure that the three sides of the triangle measure exactly the same. If they 

 do, the triangle must necessarily be perfect. Then brace it a little by nailing 

 a lath across each corner, and it is ready for use. 



Now split out some three-quarter-inch pins, one foot long, from good, 

 straight-grained redwood. Make one hundred pins for each acre you have to 

 lay off. 



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
