 California are three years old or over, this paper will be con-

It is assumed that the trees to be altered are branched fairly 

 near the ground. If they have been up high no system of 

 pruning will bring the fruit within reach from the ground, but 

 to cut out the tops will save sap and make the lower limbs, 

 such as thev are, more fruitful.

Assuming, then, that the grower has trained his trees near

 elephants to walk under, the method of procedure is as follows: 

 Draw an imaginary line around the outside of the tree, as high 

 up as a man can reach standing on a picking-box. All the 

 limbs that terminate above this line should be cut out. Cut

 the imaginary line. The sketch on page 187 shows roughly
