Herbaceous grafting has been successfully practiced ex-perimentally by Daniel,* with pea on bean, cabbage on kohl rabi, turnip, stock and other re-lated plants, fennel on wildcarrot, carrot on parsnip andvice versa, celery on parsnip,winter lettuce on wild prick-ly lettuce, spring lettuce onsalsify, salsify on scorzonera,toadtlax on snapdragon, al-mond, peach and prune oncherry.

The tubs are used to dilute these solutions. The lower barrel mixesthese two solutions which then pass as one to the spray tank through a larger hose would be a decided improvement. ♦Extended summary in Experiment Station Record, Vol. 5, p. 1089. i)ANii:i-s i-:xii-:kimi:nis and concliSions \C)y the same (inKr; .., liollDW-slcininfd annuals unite, wliilethe pith is functional; :i, uitli trees the union is easily made andthe swelling at the point of union is reduced to a minimum; grafting of herbaceous plants is most successful; 5, durationof grafted plants is more or less modified by the graft, a, annualsf)n biennials or perennials continue to be annuals, i. e., at the endf)f the growing season they die and cause the partial or totaldeath of the stock; b, biennial grafts with rare except
