THE WHEAT CUETrUIST. 



say that, for the most part, theories touching wheat 

 have been promnlgated jrom year to year, by men who 

 neyer raised a bushel of wheat, and who were utterly 

 ignorant of the fnndamental principles of agriculture. 

 On this subject, I herewith copy a few paragraphs from 

 a work written by J. Distm-nell, on the Influence t)f 

 Climate, for the purpose of showing how common it is 

 for writers to reiterate, for well-established facts, cer- 

 tain theories that are palpable absm-dities. The writer 

 says : 



The limits of the cultm-e of wheat and the common 

 cereaha are not so weU defined in the United States, and 

 Canada and other portions of British America, owing to 

 tJie want of correct meteorological obseryations in the 

 different pai-ts of this extensiye and unexplored region. 

 It is safe, howeyer, to say, that in Canada it extends 

 north as fai* as the 48th parallel of latitude, Irom the 

 Bay of Chaleurs to near the mouth of the Saguenay 

 Eiyer, and from thence to the Lake St. John, 48 deg. 

 30 min. north, including the yalley of Lake Temiscaming 

 and aU the head sources of the Ottawa Eiyer, extending 

 to MieliicopL'teii Bay. situated on the north shore of Lake 

 Superi : : . -7 : ^ . .: min. X. lat., haying mean summer 

 tempera: lire oi 59 deg. Fahr. 



"To the west of Lake Superior it embraces the yalley 

 of the Lake of the TToods. on the 49th parallel, running 

 northward and embracing the whole of the yalley of 

 Lake Winnipeg, eleyated 700 feet aboye the ocean ; and 

 the great yalley of the Saskatchewan Eiyer, extending 

 stiU farther northward to the 60th parallel of north 

 latitude, in the yalley of Mackenzie's Eiyer. To the 

 west of the Eocky Mountains, in the northern part of 

 British Columbia, and on the Island of Sitka, 57 deg.
