' A\ OUTLINE OF piivtobiolo(;y. 39 



These papers were addressed to tlie local botanists of 

 Acadia : in concluding, I wish again to commend to them 

 for study this subject of Plant-adaptation. All Avho wish 

 to keep abreast of the advance of botanical science must 

 give it careful attention. But those who would excel 

 must do more ; providing themselves with good books as 

 guides, sharpening the powers of observation, reasoning 

 and experiment, setting before themselves as the ideal 

 the studN' of the plant alive, in action, and in touch with 

 its surroundings, they must systematically, constantly and 

 intensely devote to it their best powers.
