Floriculture; Florists. 304 The American Florist, Mar. 28, German florists subsequently took an interest in the subject, and one of them from Hamburg went to Copenhagen and studied Dr. Johannsen's experiments there. It had been admitted by these florists that the great firms would be obliged to use ether for early forcing, especially so as the economy of fuel in forcing etherized plants covers the cost of etherization itself, and also because lilacs may be forced into bloom in eighteen days after removal to a warm atmosphere. One of the principal firms in Hamburg had proved:—(1) Thatether- ized lilacs force most rapidly; (2) Some varieties that are known to be difficult of forcing may be forced after etherization as successfully as the variety Charles X.; (3) That some lilacs not specially pre- pared for forcing had been lifted from the open, etherized, and subsequently forced with capital results. M. Lemoine described experiments that had been made in France last year with chloroform as well as ether, and although it is probable that chloroform may be used in some cases in place of ether, the results were not altogether satisfactory or conclusive. They, however, appeared to show that the amount of chloroform which was used was excessive, and that its influence is of much greater degree than that of ether, probably to the extent of three parts in four. Reference was next made to the results obtained by Mr. Jannoch, a nurseryman at Dersingham, Norfolk, whose experi- ences have been "quite beyond anticipa- ; It is obvious that the import- ance of the vapor of ether in relation to the forcing of shrubs is only applicable to very early forcing, that is, at a season previous to Christmas, for after the com- mencement of January, when the plants have reached the third stage of rest described by Dr. Johannsen, forcing by ordinary means may be done successfully.
