down at 2s. 6d. per day. Now let us see how this pays the planter. Mr. 
Cowley estimates the return of pure commercial coffee bean at 2°97 oz. from 
11b. of ripe berries.* Let us value the commercial bean at 9d. per Ib. 
Taking the average day’s picking by one man at 60 lb. of berry, this gives, 
at the above calculation, 180 oz. or 114 1b. of commercial coffee, which at 9d. 
per lb. is worth a fraction over 8s. 5d. 
From this we deduct the wages of the picker, 2s. Gd.; and we now have 
5s. 11d. to represent the profit of the man’s labour to the planter. Out of this 
5s. 11d. has to come the cost of clearing, planting, and cultivation of the land, 
interest on outlay for over three years, cost of manufacture, interest on outlay 
for machinery, cost of bags, cartage, freight, instirance, commission, and a few 
other sundries. 
At 6 feet by 6 feet apart an acre will contain 1,201 trees. Allowing 3 1b. 
of clean marketable coffee to each tree, we get 3,603 lb. per acre. At the 
above calculation of about 5 Ib. of berry to 1 1b. of clean coffee, this would 
tneah that 18,015 lb. of berry would have to be picked. The cost of thé labour 
for picking, at 3d. per lb., would reach £87 10s. 74d., and the value of the 
commercial bean produced £185 2s, 3d.; from which we deduct picking 
expenses, leaving £97 11s. 73d., from which all the above-mentioned items have 
to be deducted. 
As, however, paper calculations rarely are borne out by practical results, 
a considerable reduction may doubiless be made on the figures denoting 
returns.

Pisciculture, 
THE CHRATODUS. 
Piscrcutturists will be glad to learn that Mr. D. O’Connor of Duporth, 
Oxley, has been successful in landing four specimens of the Queensland 
Ceratodus in perfect health in London. Mr. O’Connor, it will be remembered, 
advocated, in this Journal, the introduction of the Gourami of the Mauritius. 
(Vol. I., Pt. 4, p. 840), which he described as most delicious fish, easily trans- 
ported, being very tenacious of life, and certain to do well in Queensland 
waters. An enthusiastic pisciculturist, he determined to make an attempt at 
introducing the Ceratodus into England, and with this view procured four liye 
fish from the Mary River. These were placed in specially prepared tanks on 
board the “ Duke of Devonshire,” which left Brisbane on April 16. ‘The fish 
were anxiously watched by Mr. O’Connor during the voyage home, and his 
care has been rewarded by complete success. 
Having succeeded in this venture, he intends, on his return, to obtain 
living specittiens of the Gourami at Java, and will no doubt have the satisfac- 
tion of seeitg this fish multiplying in Queensland waters.
