EQUATIONS: 



For 1% foot trees : 0.225 ^ i.oX*" = 1.52; X = 5 per cent. 



For 2 foot trees : 0.562 x i.oX*" = 4.72; X = 5^ per cent. 



For 2% foot trees : 1.750 x i.oX^° = 18.70; X = 4 per cent. 



For 3 foot trees: 4.250 x i.oX°° == 46.80; X = 4 percent. 



RESULT : The owner should dispose of all trees having a 

 diameter of 2^ foot or more, as they grow only at a rate of 4 per 

 cent. Obviously, unsound trees which are apt to deteriorate, should 

 be cut at once whatever the diameter be.
