THE DEVELOPMENT OF NEW FRUIT BUDS AND FRUIT SPURS FOR THE YEAR FOLLOWING AN ATTACK OF CURL. In February, 1894, while the action of the sulphur sprays was being considered in the Riviera orchard, the question arose as to the rela- tive ability of spraj^ed and unsprayed trees to produce fruit buds and fruit spurs for the year following a severe attack of curl.
