 or being unknown in the market with its conse-

 worth renovating only when they are in good 

 demand in a nearby local market. 



(2) Vigor is more important than age in the 

 tree, but is closely correlated with it. Ordi-

 tree more than forty or fifty years old, but this 

 must always depend almost wholly on its condi- 

 tion and other characteristics.

 justify the expenditure of the time and money. 

 This affects the results not only in expense, but 

 in economy in management, equipment, and 

 marketing. There should be at least an acre 

 of say thirty trees, and better, more than that 

 number to justify the expense of time and 

 money necessary for renovation. One hundred 

 trees would certainly justify it, other conditions 

 being favorable. Then, too, the trees should 

 be in such shape that they can be properly 

 treated without too great trouble and expense,
