in which they are grown. “Garden and Field happens to have

following may be taken as an approximate statement :— 
Carbeanet would yield from 100 to 110 gallons to the ton. 
Shiraz up to 130 gallons.

Dorodillo from 170 to 180 gallons. 
TO PREVENT RUST IN IRON TANKS. 
E. T. Smrru, Tiaro— Ea

applied to the insides of iron tanks to prevent rusting, and at the 
same time will not spoil the water? How should it be applied ?

known preventive of rust,

GUMMING IN PEACH-TREES. 
Jack, Charters Towers— 
Question.—Please inform me what causes peach-trees to discharge large 
quantities of gum from the roots (the leaves all fall off nearly), and 
what will prevent it? I found the gum wheu looking for some 
cause for the leaves falling off, as I had already sprayed them with 
Bordeaux mixture, but it did not seem to do much good. 
Answer.—The gumming in peach-trees may be caused by any one of the 
following things :— 
Ist—Severe attack of scale insects, such as San José. Remedy 
in this case: Cut back the tree, and either spray with 
sulphur, lime, and salt-wash in winter, or paint with 
sulphide of lime or a good stiff whitewash. 
2nd—Root borers. Remedy: Clear soil away, and after 
inspection for borers paint well round butt and top of 
roots with sulphide of lime. 
3rd—Bad drainage and consequent sour condition of soil. 
Remedy: Drain. 
FIGS FALLING OFF. 
E. T. Smrru, Yarrabine, Tiaro— 
Question.—I had a sucker of the White Genoa fig given me, which I 
planted near some other figs in my garden. It Hey well, but the 
figs fell off before they were fully grown. Is there any cure for 
this ? 
Answer.—The only remedy is to work over the barren tree with a 
variety that fruits well in the district. The working over is done 
either by means of budding or grafting.
