on the contrary, all circumstances which are favourable to 

 perspiration increase the power of suction. I cannot here 

 give his diagrams and reasoning more at large ; but they 

 who wish to read more know where to go for that informa- 

 tion. 



In arboriculture, as in other sciences, nothing can be per- 

 manently effected in a moment. Time does not spare what is 

 done without him. 



This is, no doubt, a valuable society, which embraces the 

 collections of individual research. It is in the power of this 

 society to inform a man of the value of his estate, geologically 

 speaking. A few months or years accomplishes the task : 

 as flint and steel produce fire, so the collision of different 

 opinions determines a disputed point in the arts, and elicits the 

 truth. An architectural society requires little time to mature 

 and bring to perfection disputed points relative to the origin 

 of the Gothic arch. With sovereign power, a building may be 

 reared in a very short time, but I do not know of any human 

 power to raise a tree in the same time, which from a state of 

 infancy is an object of great interest, and promises great 

 future reward ; and what is it that constitutes the great value 

 of our existence, but that hope ? Why do such societies as 

 the Agricultural Society exist, but for the benefit of the nation 

 at large, and through them to effect more than can be done 

 by private individual exertions ? All the above can be proved 

 in the life-time of man. If to advance the different sciences, 

 societies of men are formed, how much more is one required 

 to encourage the science of arboriculture, which demands 

 time beyond the age of man ! 



Can any consideration be more momentous than to find out 

 the best mode of cultivating the oak, the pride not only of 

 England but of the world ? Can any horticultural produce 

 be more beautiful than the wild forest tree ? it bears its flowers 

 as well as the common garden plant. A society of this kind
