Roots.--The action of frost is not thoroughly understood by farmers generally. This is shown by the way clamps are covered with manure on the top and half-way down the sides. The singular fact, however, is, that the top of a clamp is never injured--that is, unless the frost is so severe and prolonged that the whole mass is frozen--if the clamp be fairly covered with straw and earth at starting. The severity of an attack of frost begins and continues from the outer soil at the base of a clamp or brick store, as a barn or other building. Whether this is because a gentle fermentation of the roots or potatoes goes on, the warmth thus caused rising to the top, or whether it is because the lowest temperature is nearest the immediate surface of the earth, has not been decided; but the result invariably is that, if a body of roots or potatoes be partly injured, the rotten ones will be found at the bottom. If the clamp be broadside to the north or east wind, the rotten ones will be found in the form of a triangle on the side where the wind has blown, the base of the triangle being at the bottom; if, however, the clamp had been situated with the end to the wind, the rotten roots will be found at that end in the form of an inverted M, that is, there will be a decayed triangle on each side. The length and depth to which this decay would extend along the clamp would of course depend on the severity and length of the frost. The required precaution is therefore shown. In the case of clamps after several days of severe frost, with a prospect of its continuing, long manure, straw, hedge-trimming, or whatever may be at hand, should be packed 1 ft. or more thick, and 1 yd. or so wide on the surface soil at the base of the clamp, at the side on which the blast is impinging. It is the same with a brick building. If a bed or heap of potatoes or mangold be stored in a barn, either all over a bay or in one or more corners, and the same be well covered with straw, there will be no fear of the top or outer side of the heap being frozen. But the part of the heaps which are near to the wall will be found to have been frozen in the form of a triangle, as mentioned. The fact is the frost rises, so to express it, from the foundation of the brickwork being communicated with from the surface soil outside. This shows the importance of packing a body of long manure or a quantity of straw on the surface soil outside the brickwork. Rowan Berries.--(_a_) Fill a large earthenware jar with strong salt and water. Put in the berries; tie it down. They will keep in this way till Christmas, (_b_) Gum them well all over so as to make them adhere to their stalks, and sealing-wax the ends where cut from the tree, and keep them in a tin box till required for use.
