BURGUNDY MIXTURE.

* fOli POTATO SPKAYIN'O. Ordinary knapsack sprayers hold about three gallons, but probably -U gallons is as nmoh as one unused to swaying "ill wish lo carry on his hack. In oaten to meet the demands of such, ami also o£ those who have recourse to tile garden syringe (which so long as it is fitted with a no/'/.10 which will give a line mist-llkc spray, may be used for the purpose), ihc weight of copper sulphate (which should be of 1)8 per cent. ■ purity), and of washing soda required for making 2d gallons is hero given. Dissolve ioz of the copper sulphate in Jgallons, of water in a wooden vessel ; and soz of washing soda in, 11 gallons of water in another vessel not necessarily wooden), When dissolved (they must be cold) pour both together into the knapsack. ls> at once after mixing. This should spray three or four rods. Where larger quantities are required, the two solutions may be made much stronger, and as they will keep, if kept covered, quite safely for a few days so long <is they are not mixed, this, is often a convenient, wav of keeping them. In this case Ilh, say, of the copper sulphate may be dissolved in 4 gallons of water, and oil’s of rx a«l»ing soda in another four gallons. To make 2d gallons of Uurgimdv mix-’ lure, two pints of the copper sulphate arc carefully measured out and mafic up to 11 gallons with water, two pints of the wash,ng Sofia solution are made up to 11 gallons with water in another vessel, and llv hwo solutions diluted thus are mixed as la fore., and us"d immediately. Ihe more diluted (ho solutions ;Ui' before mixing, and (tie quicker (he mixture is us"d after ii is made the better. '( will not- keep.
