The best results have been obtained on the Experimental Farm at Agassiz, B. C., 

 and at Nappan, N.S., closely followed by those at Indian Head. In all three instances 

 the data indicate a good quality of factory beets from which sugar could be profitably 

 extracted. 



At Ottawa the percentage of sugar and co-eflBcient of purity are considerably 

 lower than those usually obtained. 



This I believe is due, if not entirely, certainly in a very large measure, to the 

 abnormal climatic conditions that obtained here during the past season. In the first 

 place, the rainfall (13 "45 inches) during June, July, and August was somewhat 

 greater than the average. This was followed by a precipitation of 5 -31 inches during 

 September and October, an amount not less than usual for these months. In con- 

 junction with this ample supply of moisture we find certain and notable peculiarities 

 of temperature, as follows : Exceptionally high maximum temperatures, and unusually 

 low minimum temperature for the summer months. May, June, July, August, Sep- 

 tember, and October. This naturally means sudden and great changes in temperature, 

 or in other words, speaking generally, hot day^ and cool nights. Bearing these facts 

 in mind and rememhering that ideal climatic conditions for sugar-production include 

 •d moderate and well distributed rainfall during May, June, July, and August, with 

 fairly dry weather in September and October, when the beets are maturing; and, fur- 

 ther, that a low mean summer temperature, say 60°F., with few sudden or great 

 changes in the latter part of the season, are specially conducive to a high sugar con- 

 tent, the explanation of the poor results obtained this year is not difficult to find. 



At Brandon, Man., the beets are the poorest of the series. This may in part be 

 due to unfavourable weather for sugar accumulation during the ripening of the roots, 

 but the large size to which the beets have grown, considerably over 2 lbs. each in 

 weight, is certainly against a high sugar content.
