These suckers are not supplied with fruit spurs, and are as worthless as so much bamboo. Even did they bear fruit, it would be almost inaccessible, and expensive to pick. The lower limbs, naturally the most fruitful, are robbed of sap by the superior drawing powers of the top, and fail to do their duty. To overcome these difficulties the 'open center' style of pruning has been tried, and has given good results. By Skeleton sketch of a cross-section of an open-center tree. Hair lines indicate where to cut limbs. eliminating the top entirely, the sap is thrown into the lower branches. These limbs being horizontal rather than vertical, and more or less bent, elaborate or digest the sap and produce heavy crops of good-sized fruit. This fruit, moreover, is within reach from the ground and can be economically picked. When the tree is once adapted to this form, the regular prun- ing is more easily and quickly performed, the number of limbs to be cut being greatly reduced,'and all being within reach from the ground. An explanation of the details of this system should prop- erly come under two heads: 'Pruning of young trees,' and
