covered with it), and, when cold, cork them tight and tie a parchment over every one. You must not try to hurry the preserving, or you will get a bitter jam. These walnuts may be eaten immediately, or they will keep for 10 years; but, as in course of time the fruit sucks up the syrup, they should be filled up with fresh. You might use loaf sugar in preference to brown. _THE DAIRY._ The dairy should either be an isolated building or attached to the farm-house. It must be built with a view to keeping it dry, airy, light, cool, and above everything clean. Nothing absorbs the taint of bad odours more quickly than milk. The best aspect for a dairy is the north, and while the windows admit plenty of light (which develops colour in the cream) they should be shaded with evergreens to exclude sunshine and heat. The temperature should range between 60° and 65° F., never exceeding 65° nor descending below 55°. In a temperature of 40° F., milk keeps fresh for a very long time, but the cream becomes bitter before it can be skimmed. In a temperature of 70° to 72° F., the milk sours readily and yields less cream, which latter will make a soft butter very prone to rancidity. Where the dairy is isolated, provision must be made in the building for washing the utensils. This will need much care to avoid conflicting with the conditions just mentioned. The dairy site must be well drained. The walls may be of brick, built double with an air space between, on concrete footings 12 in. thick, with a damp-course as described on p. 5. The best material for flooring is well-laid Portland cement concrete; the floor should incline gently to one corner, where an outlet can be fitted so that the floor can be thoroughly flushed at intervals. All sharp corners, and edges, and mouldings must be avoided, as they form nests for the collection of dirt. The walls may be plastered throughout with material that will make a smooth surface capable of being washed, or they may be covered with glazed tiles. Shelves for holding the milk dishes should be about 5 ft. from the floor and preferably of enamelled iron or thin slate or stone slabs. Perforated shelves afford better circulation of air. The shelves should in any case be quite independent of the walls of the room.
