760 EXPERIMENT STATION RECORD. [Vol.40 



8,209 lbs. were produced by 35 colonies, an average of 236 lbs., valued at $34 

 per colony. 



Further study showed Megachile latimanus to be by far the most useful 

 species in pollinating alfalfa in southern Alberta and .1/. perihirtQ in the dry 

 interior of British Columbia. The honeybee visits the flowers without tripping 

 them, and the action of bumblebees is uncertain. 



of two experimental shipments of bees without combs received from Ala- 

 bama, one consisting of six 1-lb. packages was 14 days en route and only 17 oz. 

 of bees were found to be alive on arrival. The other shipment, consisting of 

 three 2-lb. packages, with untested queens, arrived in good condition after 

 4 days' journey and after having been assisted a little with combs and brood 

 from other colonies produced 435 lbs. of honey and built up Into five strong 

 colonies lit for wintering. 



Experimental work was conducted throughout the winter with 2S colonies 

 wintered in the bee cellar in the new apicultural building at the Central Farm, 

 the objects of which Included a comparison of different kinds of food consumed 

 by bees during the winter and the discovery of the source or sources of the 

 hard, granulated honey, associated with a heavy mortality of bees, that has 

 been found in some winters in several apiaries in the Ottawa valley. In four 

 colonies wintered on stores collected between June 26 and July 18 mainly from 

 alsike and white clover, the bees were found to (over an average of 5.1 combs 

 per colony on April 17, the honey having granulated but little. Three colonies 

 on stores gathered between July 24 and August 8, largely from white sweet 

 clover (Met Hot us alba), covered an average of only 3.2 combs, much of the honey 

 having granulated hard. Three colonies on stores collected alter August 14, 

 principally from goldenrod (chiefly Solidugo canadensis) and buckwheat, cov- 

 ered an average of 3.8 combs and the honey was not granulated 



Wintering bees outdoors, using four hives packed in shavings in a ease in an 

 inclosure sheltered from wind without attention during the winter, continues to 

 prove BUCCessful in Ottawa, the average results of the last four years showing 

 that the bees so wintered did better than those wintered in the cellar. An 

 experiment with sealed covers is briefly reported upon. 



A cage containing live wax moths (Gallcria melloneUa) with larva?, pupaSt 

 and probably eggs was placed in the honey house in the middle of March, 1917, 

 and exposed to a temperature as low as 9° F. on March is and 19. All the 

 moths were apparently killed by the cold.
