A MOST IMPERATIVE DUTY xxiii 



But, first, it will be requisite to agree upon the species : 

 as what trees are likely to be of greatest use, and the 

 fittest to be cultivated ; and then, to consider of the 

 manner how it may be best effected. Truly, the waste 

 and destruction of our woods has been so universal,

He aptly quotes Virgil, Georgics, II, in his plea for 

 confining himself to useful, i.e. commercial species : 



Sed neque quam multae species, nee nomina quae sint,

Evelyn is such a charming companion that it is 

 difficult to refrain from accompanying him further in 

 his " Discourse," but we have perhaps proceeded far

 know that the nation is more wide awake in war time, 

 more intent on setting its house in order. Putting 

 off the work is merely to delay the time at which the 

 crops will become ready for the axe. We have not to 

 wait the hundred and more years necessary in Evelyn's
