168 QUEENSLAND AGRICULTURAL JOURNAL. [1 Mar., 1902. 
Turning to the experiment with peas, when no manure was used the yield 
was merely nominal, and estimated at £4 per acre, whilst 1s. 2d. expended in — 
fertilisers on the same area resulted in a return at the rate of £10 13s. 8d. 
per acre. These are the lessons which the farmer can teach his brother farmer, — 
and we wish it to be clearly understood that the pages of this Journal are open 
to the farmers to ventilate their ideas. This beginning by Mr. Winnett will, 
we trust, prove an incentive to others to try and increase the yield of their 
land, always remembering that artificial manures are not used like farm-yard — 
manure, viz., to enrich the soil, but to furnish direct plant-food to the growing 
crop. 
We would suggest that, when making experiments such as the above, the 
rainfall be given. 
MOUNTING FOR WHIPPLE-TREES. 
Mr. R. Jarrott, manager of the Gindie State Farm, finding that in the 
very dry climate of the Central district, about Emerald and Springsure, it is 
almost impossible to keep the ordinary style of mountings of whipple-trees tight, 
owing to the constant shrinking of the timber, has adopted a link, of which he 
writes :— 
There are several advantages in using these links. The first is they cost 
next to nothing. The second that, no matter how much the timber shrinks, 
they won’t come off, and if any of the bars are broken and a man can raise 4 
Yi 3 
tomahawk and a piece of good tough sapling, he can make a new one in about 
five minutes. 
A 
The size of the iron for the hooks will depend on the number of horses 
used. For our six-horse team the links and the S hooks are made of three- j 
quarter inch round iron ; for lighter work we use half-inch. 
It is the best plan to make the links first, and cut the timber to fit them 
fairly tight without having to force them on. Then when the link drops into — 
the nick in the bar it leaves just sufficient room for the S hooks and tracehook® _ 
The nick for the link should be at least 2 inches back from the point of the 
bar. 
A NEW AID TO AGRICULTURE. 
A series of lectures is being delivered in many agricultural counties by 
Mr. D. Finlayson, F.L.S., ona matter of much interest to agriculturists. It 
illustrates the means of helping the farmer to produce more food. for his stock 
by improving the eee pias Wane ower of the roots, mangels, swedes, turnips, 
&c., with which he feeds 
them. Mr. Finlayson is engaged in expounding the —
