AGRICULTURAL REPORT. 



because the warmest month readies but to 59^ Fahrenheit, though two months 

 were maintained at nearly this mean heat through ten years of observations. 



We append a list of the names of places beyond the limit of wheat cultiva- 

 tioH as evidence of the law of heat influencing the wheat plant ; also a series of 

 localities where it is successfully cultivated, with the period of sowing and 

 harvesting, from the northern limit to the southern bound, and from the extreme 

 eastern, in Prince Edward's island, to the southern border in New Mexico, and 

 the western, in California. The interest awakened by the study of this table 

 will, we hope, induce many observers to note with method and accuracy many 

 points concerning wheat culture of which we are at present ignorant, and ad- 

 vance our knowledge of the demands of special varieties. 



The following named places lie beyond tlic boundary of successful wheat 

 cultivation, and in the latitudes respectively appended. They have not a mean 

 of 61° Fahrenheit for the hottest month, though they lie further south than 

 Fort Liard, on Mackenzie's river, latitude 60^, which probably enjoys this 

 mean, for we find it attained at Fort Simpson, on the same meridian, though 

 nearly two degrees further north. 



Beyond the north polar limit of successful wheat culture.
