Investigations at this station have shown that grafts usually bear fruit in 4 years after the grafting operation. We receive some fruit, occasionally, in 3 years after the work is performed. It is also interesting to note that when seedling walnuts of the same size are selected, some topworked and others untreated, the grafted trees after 5 years' growth generally grow tops equally as large as the tops of the ungrafted trees. The principal improved varieties of black walnut which are being used at this Station are as follows: Stabler, Ohio, Thomas and Ten Eyck. (Note by the editor.--The cleft graft described by Prof. Talbert has been superseded in the East by other methods, chiefly the bark and the modified cleft grafts). CARE AND PREPARATION OF NUTS FOR SEED PURPOSES _By Prof. E. R. Lake, U. S. Department of Agriculture_ A nut is a seed, and a seed, normally, is an embryo plant asleep. To keep a nut-seed asleep and safely resting against the favorable time when it may awake, arise and go forth, as a vigorous seedling bent upon a career of earth conquest, requires no great or unusual attention and care save that which is necessary to maintain such conditions as will insure the complete maturing, ripening and curing of the seed, its protection against the ravages of rodents or other nut-eating animals, undue moisture and an unfavorably high temperature. In other words harvest the nuts as soon after they are mature as is possible, insure their complete curing, store them where they will be kept constantly so cool that germination cannot take place, and some nuts, as the black walnut and butternut, may germinate at a temperature just above zero (centigrade(?) Ed.) and keep them moist enough to prevent undue hardening of the tissues or enclosing structures (shell), at the same time prevent them from becoming saturated with moisture and thus rotting. Summarized, these conditions are: (a) a temperature just too low for vegetative activity. (b) A moisture content of the nut just below turgidity. (c) An immunity against ants, rats, mice and squirrels.
