almost remarkable uniformity throughout the series, and we find that all the beets, 

 save those from Lacombe (northern Alberta), are of excelle)it quality and well suited 

 for sugar extraction. 



The two highest records are from ISTappan, N.S., and Agassiz, B.C., but these are 

 closely followed by the results from beets grown at Ottawa, Ont., Lethbridge (southern 

 Alberta), Brandon, Man., and Indian Head, Sask. The season at Lacombe was par- 

 ticularly unfavourable, being extremely wet in the early part of the summer and very 

 cold weather, with frosts, setting in before the beets had begun to mature. These 

 conditions resulted in a very low i)ercentage of sugar and a low coefficient of purity. 



A new feature in this work is the comparison of beets grown with and without 

 irrigation, on the Experimental Farm at Lethbridge. The results do not show any 

 great differences, due no doubt to the fact that the rainfall was ample during the 

 early part of the season, making but one irrigation necessary and that a rather late 

 one. With a dry season there is every probability of greater differences in sugar-con- 

 tent and weight of root being obtained. The larger yield from the irrigated plots, 

 unaccompanied by any marked falling off in richness, is worthy of note. 



The exceedingly high percentage of sugar in the Klein Wanzleben, Raymond 

 ' seed ' — the strain used by the growers for the sugar factory at Eaymond, Alta., is a 

 matter of peculiar interest. The analytical data are practically identical for both 

 irrigated and non-irrigated beets.
