130 QUEENSLAND AGRICULTURAL JOURNAL. [1 Frz., 1899. 
average yield per tree was 5°95 lb. Some of the trees to which only stable- 
manure had been applied, as well as others which had received both stable- 
manure and artificial fertilisers, produced 26°5 lb., some of the latter producing 
even as much as 33 Ib. 
Mr. G. J. Hockmeyer obtained very good results upon his plantation, 
Las Mercedes, in Guatemala, with a mixture of— 
474 per cent. nitrate of soda, 
31°6 per cent. sulphate of potash, and 
21:0 per cent. double superphosphate. 
No exact figures regarding the yield are given. 
Mr. A. Brunner, Helyana Landen (Sumatra) reports that’ when coftfee- 
seedlings had been artificially fertilised they could be transplanted at the end 
of six months (with one or two branches) ; as a rule this is not possible until 
a year has elapsed. 
“ As regards the manner of applying the fertiliser materials, little need be 
said. 
In laying out new plantations, it is best to mix the fertilisers with earth 
in the holes, which must be deepened and enlarged accordingly. In the case 
of older trees, the fertilisers should be applied as far as the roots may extend, 
and turned under. In order to ensure the best distribution of the materials, 
they should first be mixed with earth; the proper quantities of this mixture 
intended for one tree should then be measured off in some vessel (old tin cans 
will answer the purpose). 
Broadcasting over the field is injudicious, as it would necessitate the 
application of much larger quantities. 
GROUND COFFEE. 
Ir is tantalising to think of what the consumption of coffee might be as com- 
pared with what it is. Advertising and canvassing is less wanted than 
honesty. Itis adulteration that lessens the demand for coffee. It has a twofold 
effect :—(1) It deprives the product of its reputation, for a decoction that 
should be fragrant and comforting if made from pure coffee is not so when 
made of the adulterated stuff sold under that name; and (2) it lessens the 
offtake of coffee by substituting something else under its name. A few 
examples will suffice to show the variety of adulteration that is still practised. 
These are taken from the report of Professor Cochran to the Department of - 
Agriculture at Washington on his analyses of a large number of samples 0 
‘“‘oround coffee” and “‘ ground-coffee compounds,’ selected in Hastern Pennsy!- 
vania. Here are some of the “ compounds” that are sold as coffee :— 
Composed of bran, cracked wheat, and a little caramel; chiefly wheat- 
bran sweetened and roasted. 
Sample bears about the same relation to coffee as wheat screenings do to 
wheat. 
Roasted sweetened wheat, 75 per cent. ; coffee, 25 per cent. 
Composed of the roasted and rather finely broken grains of wheat and 
barley. 
Sample is composed chiefly of wheat bran. 
Composed of roasted cereals and husks of cocoa-beans. 
Coffee, about 64 per cent.; pea hulls, 13 per cent.; and chicory, 23 per 
cent, 
Sample is roasted rye. 
Sample is roasted barley. 
Sample is composed of wheat, chicory, coffee, and peas coarsely ground. 
Composed of peas, about 69 per cent.; grains, 29 per cent.; and chicory; 
about 2 per cent.
