AN EASILY MADE TANK-GAUGE. 
Mr. H. R. Stephens, Toowoomba, sends us yet another mechanical 
appliance which, he says, will show exactly the quantity of water collected in 
an iron tank without the owner having recourse to the usual tapping the 
knuckles on the corrugations of the tank. This contrivance is a simple gauge 
which anyone handy with tools can easily construct by studying the accom- 
panying diagram— 
lt will be seen that the instrument records the height of the water as 
beingjat H. This is accurate—far more so than by tapping. 
SAN JOSE SCALE.—A SUCCESSFUL EXPERIMENT. 
Mr. G. I. Fletcher, Sandy Creek, Warwick, writes that he has been 
successful in getting rid of the San José Scale on his fruit-trees in a very 
simple but effective manner. Cyaniding being out of the question, he decided 
to try the sulphur and lime treatment, and, at the same time, to test the value 
of eucalyptus in combination with the other ingredients. He made a strong 
decoction of gum and box leaves, which he used to make the mixture, instead 
of plain water. A little wheaten flour was added to make a workable paint. 
This was applied to every portion of the trees in the orchard. As a result, 
there has not been a sign of San José Scale during the whole season, and Mx. 
Fletcher is now pruning the trees, and finds no scale on them. 
He says that possibly other causes, of which we know nothing, may have 
assisted in the extermination of the scale, but possibly also he may haye hit upon 
something of value to those who have to fight this dread pest. 
We sincerely hope this may be the case, as there are many growers of a 
few fruit-trees who have no means of cyaniding their trees, and to these the 
discovery of so simple a remedy would come as a boom. We hope that other 
orchardists will try it and give the benefit of their experience to fruitgrowers 
generally through the medium of this Journal.
