 iiiori' than half of that reported by other investigators, due to the fact th;it tho 

 tree had produced only a comparatively small amount of fruit. It is stated 

 (hat before an orchard of ])eaches is set out in New .Jersey the soils in nearly 

 all eases should be limed with 25 to 40 bu. per acre. 



Trees at transplanting time were pruned to whips. 1 in. stubs, and .'5 in. 

 stubs, and by leavin.u two-thirds of the top. The trees pruned to whips at the 

 timi' of plaiitini,'. 1 in. stubs or .". in. stubs, did e((ually well and made better 

 and larger trees by fall than those on which two-thirds of the top was left. 



The chief varieties grown in the State appear to be first Elberta, then 

 Reeves F.-ivorile, Mountain Ivose, and ("hair Choice.

 palm from which is gathered ratia fiber. 



'I'he wax is a by-product obtained in the production of the fiber, and has about 

 tlu'ee-fifths the value of the fib(>r. In one experiment 104 kg. of leaves gave 0.78 

 lb. of i)rei)ared wax. It is estimated that the average wax production would 

 be about 100 gm. for every kilogram of rafia obtained. It is believed the wax 

 will have a connnercial value about equal to that of beeswax.
