** If the anntial yield of each tree after ten years is 1 pound of 

 nibber;Of good class, 100,000 trees would give 1,000 centals per year 

 of good rubber. At present price of the article, these 1,000 would be 

 valued in Guatemalan money at to-day's exchange $260,500 ($115,238) 

 There is to be deducted from this : — 



Guatemalan United States 

 currency. currency. 



Cost of extraction and collection of the 

 milk and manufacture of product 

 (which together may be calculated 

 at 30 cents, per pound of rubber) 



for 1,000 centals ... 30,000 ... 13,170 



Expense of transportation to point of 

 shipment (which varies in each case, 

 but can be calculated in lands situ- 

 ated on the Pacific coast at $1.50 



to $2 per cental) for 1,000 centals... 1,750 ... 768 

 Expense for embarking, more or less, 

 80 cents per cental, or, for 1,000 



centals ... ... ... 809 ... 355

 on sales, and other expenses, ap- 

 proximately... ... ... 40,000 ... 17,560

'^Deducting the cost of $72,559 ($31,853) from the income, leaves 

 a balance of $189,941 ($83,385.) 



" According to these calculations, one crop, after ten years, will 

 produce double the amount expended during that time. Even reduc- 

 ing these figures (which are not too high) to one-half, in order to be 

 free from any exaggeration, and supposing a yield per tree of 6 ounces 

 of good product, the net annual product will be incomparably more re- 

 munerative than that which coffee under the best and most favourable 

 circumstances can yield." 



FERTILISERS FOR PINE-APPLES. 



A Florida Pine-Apple grower recommends the following ferti- 

 lisers: — 



Bright Cotton Seed Meal, at the rate of 1 ton per acre per year, 

 applied once a month. 



Grounci Bone, to be applied before planting at rate of 2 tons per 

 acre. This need not be renewed perhaps for 20 years. 



Tobacco stems, unsoaked and uncut, at the rate of 1 ton per acre 

 per year, applied twice a year. This is supplied by the trade in bales.
