I am very glad, my dear Annie, to hear such favourable accounts of your garden, and to find, by the inquiries you are beginning to make, that you really are taking a lively interest in country affairs. You say you are getting quite fond of your dairy; but that you cannot understand how it is that your cows produce so much less milk in the morning than they do at night, when there are exactly twelve hours between the milkings in both cases; as they are milked first at five in the morning, and again at five in the afternoon. I have no doubt from what you say, that your cows are kept in the cow-house during the night, and only turned out during the day, as this would account for the difference in the quantity of milk. But such a mode of management, though it saves trouble to the dairy-maid, who finds it much easier to milk the cows in the cow-house than in the open field, is bad for both the cows and the dairy; as the cows, after feeding on grass all day, cannot of course relish dry food at night, and whenever they fast unnaturally very little milk is secreted. Your dairy-maid will probably tell you that cows are very delicate, and that they will catch cold if they sleep in the open air; but from May till September, unless the weather be particularly cold and rainy, they are less liable to take cold if they sleep in the open air than if they are kept in a warm cow-house all night, and turned out about sunrise. Cows are peculiarly sensible of all sudden changes of temperature, especially from heat to cold; and, after they have been kept in a cow-house all the winter, great care should be taken to accustom them gradually to the change when they are first turned out to grass, by letting them out only for a few hours in the middle of the day; but when they are become accustomed to the open air, and the nights are warm, they are much better kept in the open air altogether, especially if there is a shed in the field, under which they can find a dry place to lie upon if it should rain.
