After telling you how to grow fruit, I must next tell you how to keep it. A proper _fruit-room_ should be fitted up with broad shelves, or wooden trays with rims in front to prevent the fruit from falling off, and divided into compartments for the different kinds. There is generally a large table in the centre for sorting the fruits, and a thermometer should be hung on one side to regulate the temperature. According to Dr. Lindley, the essential points for a fruit-room are, "a low and steady temperature; dryness to a certain point, for apples are found to keep best in a rather damp atmosphere; and exclusion of the external air:" to this he adds, that it is necessary to keep the fruit in comparative darkness, to prevent it from becoming shriveled and ripe prematurely; that the temperature of the room should not be much above 40°; and that the shelves should be of white deal, as that wood does not give an unpleasant taste to the fruit. Fruits keep best when laid separately, so as not to touch each other; and sometimes pears may be kept by packing them in fern, and grapes by packing them in jars in sawdust. Walnuts and chestnuts should be kept in rather a moist place, and covered with fern to exclude the air as much as possible, as they are much injured if they are kept too dry. I may here mention that when sweet chestnuts are sent to the table, they ought always to be boiled first, and roasted afterwards; as, if roasted without previously boiling, it is scarcely possible to cook them sufficiently to make them wholesome, without burning them. After they have been boiled, before they are put down to roast, care must be taken to prick the skins; as, if this is neglected, the chestnuts will fly about in all directions as soon as the outer skin becomes parched.
