ALASKA 



ALEURITES 



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 Office 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.
