ALASKA 



ALEUBITES 



sweet alyssum, chrysanthemums, stock, candytuft, ver- 

 benas, and marigolds are not uncommon where any at- 

 tempt is made to grow flowers. Window gardens and 

 boxes add many sorts to the list already given. 



A single season's experimentation at Sitka, under the 

 direction of the Of&ce of Experiment Stations, United 

 States Department of Agriculture, has shown that much 

 can be accomplished in horticulture if rational methods 

 of culture and a proper selection of varieties and seed 

 be followed. Walter H. Evans.
