XVI PREFACE. 



ning to grow in the spring, with their leaves just turning green, are in a most 

 unfit state to remove; for, when transplanted, their roots will not have time to 

 form a sufficient number of new spongiolesto supply the loss to which the rapid 

 pers])iration by the leaves at that season will give rise. It is upon this same 

 princi|)lc, that if deciduous plants are taken from the ground in the summer, 

 thoy are put into pots and placed in a hot-bed to recover; not for the sake of the 

 heat, but because the atmo^^phere of a hot-bed is so charged with humidity that 

 pers|)iration cannot go on, so that the vital energies of the plant, instead oi' being 

 wasted by evaporation, are directed to the formation of new mouths by which 

 to feed. 



" This is hut a brief outline of what the principles are upon which the common 

 operations of the Fruit Garden depend ; yet it is hoped that it may not be with- 

 out its use in calling attention to the rationalia of what may seem extremely 

 simple and well understood practices, but which are undoubtedly neither so per- 

 fect, nor generally so skilfully performed, as to be incapable of amendment."
