One of the arts of successful nursery or florist business is to find out something in demand, and which one can grow cheaper and better than anybody else. The English papers are noting the success of one florist who has given up everything else for Mignonette. No one can grow it as well and as cheap as he, and as there is a good demand for the London market, he sold last season twenty-four thousand pots of this sweet plant. We have in our country some who have acted on the same principle and grown wealthy. There is the Dingee Conard Company in the rose specialty as an illustration. They found their circumstances just suited to the cheapest possible production of the plant in first-rate quality. They have sold low accordingly, but still profitably, and have their reward.
