984 EXPERIMENT STATION RECORD. 



Graftmfi.—nere are considered the effects of grafting, aftiiiity, the 

 structure of the grape cane in its rehition to grafting, and the like. 

 The different methods of graftiug are described and illustrated. The 

 time of grafting, choice of scions, and care of grafted vines are 

 discussed. 



Xnrseries.—Uwder this head are considered the choice and prepara- 

 tion of the soil, planting, transplanting, and similar operations. 



Lilium harrisii and the electric light ( Garden and Forest, 10 {1897), 

 No. 478, J). 1:'>7). — A report is given of an experiment made at Cornell 

 University on the effect of electricity on Easter lilies. A bed of lilies 

 was kept under uniform conditions, except that one part was exposed 

 to the direct light of a globeless arc lamp, another to the light of the 

 same lamp after passing through a pane of glass which cut out some of 

 the ultra-violet rays, and another was shaded from tlie light. The light 

 burned from 5 p. m. to 6 a. m. for four months. 



The plants of the lighted parts grew taller and more spindling, had 

 narrower, lighter-colored leaves, and were more subject to disease than 

 those in the shaded part. The plants in the direct light showed these 

 effects most. The flower buds in the naked light showed dark-brown 

 streaks on the side toward the light, the burns enlarging as the buds 

 expanded. In the naked light the flowers appeared earliest and lasted 

 9 days. . In the screened light they appeared I days later and lasted 

 9^ days. In the shaded part they appeared 9 days later and lasted 11 

 days. Plants taken from the shaded to the lighted part, after their 

 stems were well developed, blossomed 7 days earlier than similar plants 

 left in the shaded portion. They were perfectly healthy and lasted ;is 

 long as those in the shade. The conclusion arrived at is that when 

 buds of these lilies are an inch long it will probably pay to use the 

 electric light to hasten their expansion, but the light should pass 

 through glass to prevent injuring them. 



Forced asparagus, G. Wythes (Gard. Chroii., ser. 3, 21 (1S97), Xo. 533, pp. 201, 

 202). — A method of forcing asparagus in permanent beds is given. The beds are 

 long, narrow, raised above tlie level, and with narroAv, deep trenches between tlu-ni 

 filled with tree leaves to furnish heat. The beds are covered with shutters or litter. 



Burdock as a vegetable, I. XrroBE {Garden and Forest, 10 {1S97), JSo. 477, pp. 

 143, 144). — Remarks on the use of burdock as a vegetable by the Japanese. Its 

 chemical composition is comi)ared with that of some other vegetables. Notes on 

 culture, varieties, and methods of cooking are included. 



Popular varieties of celery {Amcr. A<ir. {mid. cd.), 59 {1807), No. IS, p. 54S,Ji(/8. 

 7). — Illustrated notes on several varieties. 



Hot water under pressure, J. D. Eiselk {Florists' F.rchange, 9 {1S97), Xo. 15, pp. 

 3S0, 381).— An address read before the Philadelphia Florists' Club. It discusses at 

 some length the relative merits of elevated and depressed boiler systems for hot- 

 water heating of greenhouses. The elevated boiler system is recommended. At 

 Riverton, New .Jersey, during the months of January, February, and March, 1896, 

 the cost of fuel for heating a large greenhouse by steam was $10 per 1,000 ft. of glass 

 surface. The cost for heating a similar house by hot water was $8 per 1,000 ft.— a 

 saviug of 20 per cent in favor of hot water.
