In small waters, where is the greatest danger of frost, observe never to put in stock, but the last week of February, or beginning of March; for then they take less hurt in removing, and they may be taken out in October after, and so all hazard of frost prevented; and if you venture them there one winter, be sure never let them run the hazard of another. So you have two summers feed, which will raise a carp from store to the table, and venture but one winter’s frost; and in winter they neither feed nor grow any thing considerable. _Of the ordinary Benefits and Improvements by Fish._ These were touched when I spoke of disposing the increase of fish; that is, furnishing your table, obliging your friends, and raising money. I shall only add to the last, that it is most reasonable, if it can be contrived, that pleasures pay for the charge of them. Then what is more justifiable, than to make ponds yield a profit to answer the great charge in making them? But we must go farther: ground shall be vastly improved by fish, and shall be intrinsically worth, and yield more this way, than by any other employment you can give it: for suppose it meadow of two pounds per acre (which is an high value for the best meadow far from London), I will justify, that four acres in pond shall return you every year one thousand carps fed up, from — to fourteen or fifteen inches, besides pikes, perch, and tench, and other fry, useful on many accounts, if the water suits them. The carps are saleable, and will bring perhaps twelve pence, but in all likelihood not less than nine pence; yet, let it be six pence apiece, there is twenty-five pounds, which is six pounds five shillings per acre; a little charge of carriage perhaps to be deducted. This is improvement enough.
