The following will enable an estimate to be made of 
probable profits from this source: 
111 Para rubber seeds = 1 lb. 
12,432 „ „ „ = 1 cwt. 
248,640 „ „ „ = 1 ton. 
The kernel — i.e., the decorticated seed — is 60 per cent, 
of the total weight of seed, therefore 414,400 seeds will 
make a ton of decorticated seed. At 400 seeds — i.e 133 
fruits to the tree — 414,400 seeds will be the crop of 1,036 
trees, which at 193 trees to the acre — i.e., 15 feet apart — 
is the produce of 5.4 acres. One acre will therefore give 
3 cwts. 79 lbs., value £1 17s. or $15.88.
