 . 129. Top. A hillside pasture made doubly fruitful by grafting suckers of chestnut trees in a clearing—. 130. Bottom. Tall-headed pecan trees planted by owner in cow pasture of rented dairy farm. The two stakes support the tree. The barbed wires keep the cows from rubbing the stakes. The pieces of old rubber hose by the man's finger protect the tree from the stakes. This invention is freely given to the public. The trees were mulched and manured. They are thriving in the pasture of a 'rented farm. No overhead cost. The latest improvement, in this technique in land too rough to do as in Fig. 23 is to dig a two-bushel hole above tree, plow furrows leading water to it for shower irrigation. Try it. (Photo J.
