 slacked by the <jra«lnal addition of water. 
 
 For convenience Ht ck solutions of milk of lime and bluestone 
 should be prepared an.l kent in different bar.els in readiness for s„rav- 
 in- operations. In barrel "So. 1 , 25 r,ound.s of fresh lime are gradually 
 slaked, and barrel made up to 25 gallons of water; in barrel No 2 4 
 lbs. of copper sulphate, or bluestone, are dis.solve<l in 25 .'allons of 
 water. For rapid dissolving n.se warm water. These are the stock 
 solutions. Each gallon of milk of lime contains one pound of lime 
 and each gallon of bluestone .solution contains one pound of bluestone' 
 \\hen we wish to make up a barrel of Bonleaux mixture, we take 
 out 4 gallons of iiulk of lime, and 4 gallons of bluestone solution, and 
 either dilute each m .separate barrels in 20 gallons of water before 
 mixing m the barrel attached to the spray-pump, or else pour each 
 separately into the barrel in which »re already 32 gallon.s of water, 
 riie first method is the preferal)le one. 
 
 •11 ^-^.^^^^ "**^ '^« roncpntnited dork solutvms toqpAher If the 
 milk of lime and bluestone are mixed in the concentrated form just 
 as they are taken from the stock solution, a precipitate of a flu'kev 
 naturewd! soon settle out, and either fall to the bottom or clo.r the 
 nozzle. " 
 
 3. Te>*t the liordenox to find out ivhfthei- suffieient mill of limp 
 hns been added This is most easily done by means of the ferrocvanide 
 test. A .saturated solution of this substance can be purcha.sed at any 
 druggists for a few cents. In testing, place some of the Bordeau.x, 
 which has been thoroughly stirred, into a saucer, and add a few dnjps 
 ot the ferrocyanide. If sufficient lime has been used, no di.scoioration 
 will appear, but if insufficient, u deep dark brown color will be pro- 
 duced. '
