COOPER'S POWDER, if kept in dry storage, cannot possibly deteriorate, and after twenty years would prove quite as EFFECTIVE as when froshly made. This is a GREAT ADVANTAGE, for the exigences of trade often involve long storage, during which liquid and paste Dips leak out, dry up, or cake. FIFTY-FIVE YEARS' use of COOPER'S has shown that it CLEANSES tho akin and KEEPS IT CLEAN, the result being that the skin is thus rendered better able to per- form its functions. One of these functions is the secretion of the yolk, which is infinitely more effective in preserving the wool than "soft soap," which some inex- perienced makers put in their preparations, and which is afterwards freely WASHED OUT of the fleece by the rain, and is apt to thus carry away a proportion of tho natural yolk with it. Like many of the best articles in use, COOPER'S DIP is imported. But sheep- owners, who depend entirely on the English market for the sale of their products of wool and mutton, ought to be tho last to object to tako a trifle like Sheep Dip in return ; anyway, the appeals to "Patriotism" BY INTERESTED LOCAL DIP MAKERS are not likely to influence sensible men. The reputation of COOPER'S SHEEP DIP does not rest upon one or two trials, adjudged upon ONLY A FEW WEEKS AFTER DIPPING. The Great Sheep Dip Trial of the World commenced nearly sixty years ago, and has boon carried on with increasing vigor over since, and each season during that long period COOPER'S DIP has GAINED upon all its competitors (only 'ast year tho certified INCREASE in its 3 ales boiug alone sufficient to dip over 36 MILLION SHEEP) until it is now used on over |40 MILLION SHEEP annually — more than all other manufactured Dips put together. With such a magnificent " Sheep Dip Trial " as this, the Proprietors of COOPER'S DIP are well content. VERY SATISFACTORY FOR A NUMBER OF YEARS. From Mr H. T. WINTER, Station Superintendent of N.Z. Loan and Mercantile Agency Company, Limited, Christchurch. 4th April, 1891. " T HAVE much pleasuro in Btating that J_ I havo used Cooper's Dip for a number of years with very satisfactory results, and I have found it better than any other I have tried.
