THE FRUIT INDUSTRY.

APHIDES AND MANUBE

To show tiie effect of the manure on a peach tre6 attacked by aphides (says the Sydney "Mail") the following case is taken. After, the,manure ha» Been allied,1 ttriil thl6 laity glaiie appeared tin the leaves tho aphides disappeared altogether, and the trees took on * healthy appearance. .Chemical observation showed that this Salty glasiS was Uißtiiiiifcly Uistabicfui to insect life. This experiment was also borne out to a certain extent by the writer, who used kainit this season as a top-dressing for" tbnlatoss. Previous--I,V) tOmiitoGi; grevfri iti the iiftia wfere always ba<Jly affected with tomato rot which belongs to the same low-grade fungoid class as bitter pit. During the earlier part of tho year, when the moisture was not sufficient for the purpose, a top-dressing of kainit was dissolved in water. a.Binall amount of nitrate of .fißd'A being added, and. the. soil sprayed with the mixture, one pint to each tomato plant. The result rightthrough was striking, showing that, besides acting as a stimulant and a | fertiliser, it had also ridded the fruit outire'y of rot and aphides. Every leaf of the tomato plants was coloured by a clearly perceptible glaze, and the leaves had a distinctly salty taste. Canadian experiments, which were /cry careful, went to show that whore kainit is freely applied it will disappear on the surface of the leaves.
