IMPLEMENTS 



other experimenters have found such results as 

 leave it still a problem whether it can be used to 

 advantage. Some experiments made at Ithaca, 

 N. Y., indicate that it is better to intermit the use 

 of the electric lamps during some portion of each 

 night, and always on moonlight nights. The 

 employment of the ordinary white opal globes 

 to temper or modify the bare unshaded light 

 (when run continuously) also appeared, in those 

 experiments, to be beneficial, but I have not used 

 them. 



For the forcing of asparagus and other peren- 

 nials, permanent outside beds are sometimes used. 

 These beds are so constructed as to afford a sub- 

 stitute for the more convenient but highly expen- 

 sive equipment of hot-houses having water or steam

Where such a bed is proposed, the plan gener-

 bricked up on the outside and filled with stable 

 manure. As often as may be required by the tem- 

 perature, the manure is renewed. The bed may
