As a great garrison must have many subservient forts and redoubts dispersed about the place, for securing the country, and collecting the contributions, which are to maintain the head-quarters; so the great ponds, which are the head-quarters of the fish, must be accommodated with many other subservient waters, which I call auxiliary, because they serve to relieve the greater when over stocked, to supply them when under stocked, and to rear up and maintain fry and young stores, as well as to render the fish easy to be taken; without which conveniences, you will have but a sorry account of the fish. There are stews, moats, and ordinary ponds dispersed about in your estate and neighbourhood; the employment of which being very considerable in the well ordering of fish, I will consider each apart; and first, of stews. _Of Stews._ The peculiar use of these, is, to maintain fish for the daily use of your house and friends, whereby you may with little trouble, and at any time, take out all or any fish they contain; therefore it is good to place them in some inclosed grounds near the chief mansion-house. Some recess in a garden is very proper, because the fish are fenced from robbers, and your journey to them is short and easy, and your eye will be often upon them, which will conduce to their being well kept, and they will be an ornament to the walks. If you have two great waters of three or four acres apiece, I do advise, that you be not without four stews, of two rods wide and three rods long apiece. The way of making these, is, by cutting the sides down somewhat sloping, and carrying the bottom in a perpetual decline from end to end, so as you may have a convenient mouth, such as horse-ponds usually have, for taking out your nets when you draw for fish. If you have ground enough, it is better to make a mouth at both ends, and the deepest part in the middle; for so you may draw your nets backwards and forwards, losing less time, and the fish will not have such shelter, as the depth under a head will be. Besides this, you will find the fish will delight themselves in coming upon the shoals, and it may be, thrive better. But for this manner you must allow at least a rod of ground in length more than for the other. These I intend for carps chiefly, though not absolutely; and if you find the tench and perch increase and prosper, you may make other lesser stews to accommodate them apart, if you please; and so you will have them at command, without disturbing the other fish; only observe this by the way, that perch will scarce live in stews and small waters, if the weather be hot, but will pine, grow lean and thin, if not die; therefore the stews are to be their winter-quarters; from whence you take them for the use of your table, but in summer translate them to the greater ponds.
