The bundles of bud sticks are packed in properly moistened, sterile, sphagnum moss and delivered to the propagators as soon as practicable, in order to avoid possible injuries from storage. In this way trees of the best lemon strains are being propagated, so that the production from orchards planted with these trees can reasonably be expected to be uniformly of the best type and quality, thus insuring the best possible economic results to both the producers and the consumers. SUMMARY. The important commercial lemon varieties now grown in California are the Eureka, Lisbon, and Villa Franca. The Eureka variety originated from a seedling in the city of Los Angeles about I860. Several important strains of each of the varieties have arisen through the unintentional propagation of bud variations. In this bulletin only the variations within the Eureka variety are discussed. Descriptions of variations in the Lisbon lemon will be found in United States Department of Agriculture Bulletin No. 815. Bud variations are of frequent occurrence in some of the trees of the Eureka variety. They are of great importance to the lemon industry in that some of the strains which have developed from them are inferior in quantity and quality of production. Bud variations are much more common in lemon varieties than has heretofore been thought to be the case.
