"There, in his aerial garden, Mr. Lockroy successfully grows pears, currants, gooseberries, and roses; and, on the testimony of M. Carriere, the plants are as vigorous and healthy as could be wished, and produce fruit and flowers of quality and beauty equal to terrestrial subjects. Of course they require a great deal of care, and much labor; but the labor is a labor of love, and Mr. Lockroy appears to understand what treatment suits his pets, and permits nobody else to touch them. He cultivates no fewer than eighteen varieties of pear, and successfully fruits them all, including such varieties as Winter Doyenne and others which commonly get spoiled, but not in the aerial garden of the Rue Washington."
