As soon as the plants are first ridged out, have dung in for a lining, which should always be put in the front and sides first. When the dung has been put together a week, turn it, and at the end of another it will be fit for use; one load being sufficient for a three-light box. After the plants have been ridged out a fortnight, or three weeks at the farthest, it will be necessary to line the bed to the width of about two feet, and three parts as high as the bed, inclining with a slope of about six inches towards the top. When the dung has been put about half way up, tread it, and then add the remainder, beating it well down with a fork. Cover the lining with litter about three or four inches thick at the outside, and within one or two inches of the top of the box; then place a board at the top about nine inches wide, which will keep it close, and assist in drawing up the heat. Be particularly careful in stopping the inside next to the box, when you make a fresh lining, and beat it close down with the hand about two or three inches above the bottom. When a fresh lining has been added, have the dung in readiness for the back, which will be required about a fortnight afterwards. It should be formed about two feet six inches wide, well trod down, and wrapped up in the same manner as the front, within three inches of the top of the box. Be careful that the litter is not rank; old useless hay, or litter that has been some time laying by, will be preferable. The same directions must be attended to in stopping up the inside of the box, as with the front. As soon as the heat of the lining in any degree affects the bed, and you discover that the inside, where it has been stopped, begins to get dry, give it some water in the evening, just before covering up, for about a week or ten days, which will be the means of keeping the rankness down, and causing a sweet steam heat to rise. As the lining settles, press it down with a spade next the box, and add more litter upon the top, which should be done every other day, observing that when you increase one lining to have the dung in readiness for the next; each lining not being calculated to last more than a month or five weeks; though the back one will not want renewing quite so often as the front. When you apply the second front lining, it will be necessary to bore the bed with a hedge-stake or mop-stick, making five holes to a three-light box; that is, one under each hill, and two under the bars: bore them straight rather better than half way up the bed, so that when the second back lining is applied, holes may be bored exactly opposite to the others. This will cause a free circulation of the heat from one lining to the other, and prove not only of great service in regulating the temperature of the bed, but of equal advantage in draining off the surplus water. Take care when you add a fresh lining, to keep the holes open.
