Several per- sons investigating independently within the past two years have i^ro- duced excellent results from carefully selected buds, modifying in several respects the methods usually adopted in budding (figs. 13 and 14.) While not san- guine enough to publish results, some experiment- ers believe that we are soon to witness a decided change in the method of budding, which will dis- place, especially in luirs- er}?^ propagation, the pres- ent unsatisfactory prac- tice of crown grafting. During 1910 less than 20 per cent of the nursery grafts effected successful union, and in a few in- stances propagators who had formerly secured as high as 50 to GO per cent of unions were rewarded with less than 10 per cent. The low percent- age of " takes," together with the heavy expense of operation in crown grafting, makes it desir- able to adopt another method. To stimulate experi- ment along this line, at- tention is called to a few points found useful last year. One worker found that the use of dormant buds upon the present year's growth during July resulted favorably. He adopted the usual method of budding, but made the crosscut at the bottom instead of at the top of the slit. Another recommends chijD budding (fig. 15), with bicj^cle tape * for Avrapping material. This operator finds it necessary to use buds that are fully dormant, preferably those which have been 1 Bicycle tape gave very unsatisfactory results in budding operations at the Arlington Experimental Farm In 1912. 264.
