they would bear exposure and the injuries of trans- 

 planting at the same time? Sir Henry Steuart 

 mentions some particular facts as causes of this un- 

 suitableness. Perhaps it would have been as well 

 to ascribe it to general inaptitude and delicacy, as 

 there are several other circumstances not easily un- 

 derstood, such as vital stamina, habitude or accli- 

 matizing, and texture and configuration of vessels, 

 which must have influence. We should also think 

 simple evaporation of the fluids of the transplanted 

 tree a much greater cause of its failure than the cold 

 of this or of any other evaporation acting to numb 

 the sap-vessels in the stem and branches. The ab- 

 sorbing mouths of the rootlets, excepting in the case 

 of very large balls, are generally destroyed by the 

 operation of removal ; and the development of the 

 leaves to a certain extent taking place before any 

 new process of striking of the roots, owing to the 

 atmosphere and branches getting sooner heated in 

 spring than the ground and roots, the half-de- 

 veloped leaves shrivel up in the arid spring air, from 

 the evaporation of the juices and deficiency of root- 

 suction ; and when the air gets moist, showers fall, 

 and the earth becomes warm enough for the strik- 

 ing of the roots, the vital principle is too far spent, 

 or the material substance too mucH changed, for the
