$f&amp;gt;ped on the fides fo as to bring it to eight or ten on the top. It is better, how 

 ever, to have the fide next to the water more doped than the other. Some fuch 

 proportion as this fhould be preferved in all cafes, always giving them too much 

 rather than too little breadth in their foundations. Pioper grates, flu ices,- and; 

 diverting channels for taking off the water in the time of floods will like wife be 

 eceffary ; the laft being formed and conducted along the fides of the ponds, wheie 

 there are more than one, and the flu ices fixed in the loweil parts. Thefe iliould 

 be made perfectly (trong, of good feafoned oak, and be well fixed in the banks, and 

 the clay tightly rammed in about them.* 



The expenfe of conflrucTmg heads and banks of this nature, including every 

 thing, may in moft fituations be eftimated at from one to two fhiilings the cubical 

 yard. 



In railing carp it is often the practice to have three ponds : one for the purpofe of; 

 fpawning the fifli in, and in which they fhould be left during the reft of the furnmer 

 and the following winter, as they moftly fpawn from the beginning of May to thelat* 

 ter end of July ; another for the convenience of nurfing up the young fry, into which 

 they mould be put about the latter end of March or the beginning of April, choofing 

 a calm but not funny day for the bufinefs. After which they mould be carefully 

 prevented from coming to the fides and being deftroyed* In this pond they may 

 remain two years, and become four, five, or fix inches in length, and good for ufe; ; 

 the third or main pond is deftined for the reception of the grown fim, as thofe that 

 meafure a foot or more, including the heads and tails. 



The proportions in which thefe different ponds are advifed to be flocked are 

 thefe: for each acre of the firft fort, three or four male carps, and fix or eight 

 female ones.&quot; The moft fuitable fort for this ufe being thofe of five, fix, or 

 feven years old, in good health, with full fcale, and fine full eyes, and a long body, , 

 without any blemifh or wound.&quot; The ponds fhould beprevioufly cleared of all forts 

 of voracious fifhes and other animals, as perch, pike, eel, and trout; the water- 

 beetle, and alfo the newts or lizards. f&quot; Such ponds as are warm and have an open &amp;lt; 

 expofure,with foft water, are the moft proper for this ufe, all kinds of water fowl be 

 ing kept from them. For the nurfing ponds a thoufand or twelve hundred may not be 

 more than fufficient for an acre, andfor the main ponds, one to every fquareof fifteen 

 feet is the proportion advifed, as their growth depends greatly on the room and quan 

 tity of food thatis allowed.* Thebeft feafons for performing the bufinefs in this cafe
