Saunders, W. and Ch. E., Results obtained in 1909 on the 

 Dominion Experimental Farms from trial plots of Grain, 

 Fodder Com, Field Roots and Potatoes. (Bull. 64, Dept. Agric. 

 Cent. Exp. Farm Ottawa, Canada. p. 1—53, Nov. 1909.) 



This bulletin gives the results of trials that have been under 

 way for a number of years at the older experimental farms of the 

 Canadian Department of Agriculture. In almost all cases the average 

 3 r ield at the Station in question for the past five years is given as 

 well as that for 1909. In case of the cei'eals and peas the average 

 number of days required for maturing is also given. 



The experiments were conducted at the following stations : Cen- 

 tral Experimental Farm, Ottawa, Ontario. (11 crops, 118 varieties.) 

 Nappan, Nova Scotia. (11 crops. 133 varieties.) Brandon, Ma- 

 nitoba. (11 crops, 131 varieties.) Indian Head, Saskatche wan. 

 (11 crops, 137 varieties.) Lethbridge, Alberta. Irrigated (12 

 crops, 129 varieties.) Non-Irrigated. (11 crops, 100 varieties.) La com be, 

 Alberta. (11 crops, 132 varieties.) Agassiz, British Columbia. 

 (11 crops, 133 varieties.) From three to twenty varieties of each 

 crop were tested. 



The present bulletin is the fifteenth of the series giving the 

 results of this series of tests which are probably the oldest series 

 of such trials carried out under a uniform plan in such widely dif- 

 ferent localities in North America. 



One of the most remarkable results is announced by the authors 

 as follows: "The results of average crops obtained for five years 

 indicate also that the tendancy to productiveness is in most instan- 

 ces persistant, manifesting itself under varying conditions of soil 

 and climate to a remarkable degree." 



This series of tests deserves attention in other parts of the 

 world. W. T. Swingle.

 [Bericht über die Arbeiten mit Gerste im Jahre 1908]. 

 (Sveriges Utsädesförenings Tidskrift. 4. p. 211—220. 1909.) 



Zunächst giebt Verf. eine orientirende Uebersicht über die Ent- 

 wicklung und den gegenwärtigen Stand der von den Svalöfer 

 Saatzuchtverein in den späteren Jahren mit Gerste vorgenommenen 

 Arbeiten, sowie über die bei denselben befolgten Grundsätze. 



Namentlich hat sich das Bestreben geltend gemacht, aus den 

 alten Landessorten geeignete neue Sorten zu isolieren und zu züchten ;
