The above figures speak for themselves, and furnish sufficient proof of the 
fact that a correctly proportioned artificial fertiliser has as beneficial an effect 
as the average applications of stable-manure. 
Stable-manure in combination with artificial fertilisers gave the highest 
yield.

QUEENSLAND NUTS. 
By E. COWLEY, 
Manager, State Nursery, Kamerunga., 
Mr. E. Cowxey proposes to furnish a series of short articles on some of our 
North Queensland nuts, and these notes will doubtless prove interesting to the 
readers of the Journal. 
No. 1—THE CANDLE NUT. 
The so-called “Queensland nut,” Macadamia ternifolia, F.v. M., does not 
apparently extend to within the tropical portion of our colony, but belongs to 
the extra-tropical division. The same may be said of two other members of 
this family—viz., Jf. Youngiana (which is found at Maroochie, and reported to 
be poisonous), and M. verticillata, which is reported from the Pine River. 
These nuts belong to the natural order Proteace. Our own nuts belong to 
other tribes. 
To begin with what is probably the best known of our North Queensland 
nuts, the candle nut (Aleurites moluccana, Willd., or Aleurites triloba, Forst.), 
belonging to the natural order Euphorbeacew. This tree grows to a large size, 
rising to 70 or more feet, with a diameter sometimes of 3 feet at the base, in 
our scrubs. It is a soft wood, but sawmillers often use it for cutting into 
boards for fruit-box-making, notwithstanding that it is rather heavy when it is 
sawn. It dries in a short time, and makes up into excellent fruit-boxes, having 
the great advantage of not splitting when nails are driven in near the ends. 
Tt seems a shame, however, to sacrifice such a valuable tree for fruit-cases ;
