ELECTRICITY IN RELATION TO HORTICULTURE.

we have a favourable percentage of these rays, and that in these or in 

 the kiminous rays present we have a forcing agent of no mean vakie. 



These lamps are somew^hat expensive, but they have been largely 

 employed in factories and workshops. They should run with little 

 attention, and are very easy to start up in the evening, and a trial with 

 them might be v^ell w^orth the while of a horticulturist who has available 

 the necessary direct current at the normal voltages. 



This is an impatient w^orld, so that any factor which tends to 

 accelerate production cannot be neglected by the grower, even though 

 it tends to make life more strenuous than it was before. 



With this in view I have attempted to give an account of two appli- 

 cations of electricity which may prove to be of service in accelerating 

 crop production. At present, however, their appeal is rather to the 

 grower with time and money for experimental work than to the man 

 whose chief desire is a certain method of increasing his profits.
