sinks into partial inaction, but only of those when she is in full 

 activity. 



The following table, condensed from the Canadian Year Book 

 for 1868, will enable the reader to follow these changes duritig the 

 five warm months, and to effect a comparison of the mean summer 

 temperature in various parts of the Dominion. It also serves to 

 show that the summer temperature of St. John is comparatively 

 low. It is probably this, and the want of any observations by 

 which an estimate of the climate of the interior could be formed, 

 which has led the author of that portion of the Year Book from 

 which this table is drawn, to include the whole of New Brunswick 

 ia the same climatic division with Prince Edward's Island, and 

 that portion of the south shore of the St. Lawrence between Gasp^ 

 and Quebec. As regards the northern part of New Brunswick, 

 this would appear to be a natural division ; but when the climate 

 of central New Brunswick is better known, I am inclined to think 

 it will fall within the division comprising the eastern townships 

 and that part of Upper Canada between Lake Ontario and the 

 Ottawa River. Instead of falling within the region where wheat 

 can scarcely be grown with profit, this portion of New Brunswick 

 is likely to be recognized hereafter as a country much more favor- 

 able to farming operations than might be inferred from the classi. 

 fication given in the work above cited. It is distinguished from 

 other parts of the Province by the presence of a group of plants, 

 which indicate a climate in which Indian corn can be brought to 

 perfection. The analysis of the Acadian flora given on succeeding 

 pages will, it is believed, fully bear out this opinion. 



Not only the coldness, however, but the humidity of the 

 atmosphere, in many parts of Acadia, exercises a powerful 

 influence upon its flora. 



It is a well-known fact that the land and sea breezes which
