22 On Stocking. 



The two items remaining are rent and manage- 

 ment, if the cost of construction is considered 

 part of the water supply, and is included in 

 the moderate calculation of one-tenth of a penny 

 per thousand gallons. The ponds, with the 

 necessary ground between and around them, will 

 require between two and three acres, and the in- 

 terest of cost of roads, fences, and buildings, 

 mincing machinery, etc. , falls to be treated as rent. 

 I do not think that less than 30 per annum can 

 be calculated on, omitting management, risk, and 

 profit, the balance will stand : 



Per Annum. 



Stock, . . . 60 

 Food, . . 200 

 Labour, . . . 160 

 Rent, . . . 30 

 Water supply including con- 

 struction of ponds, . 456 5 



906 5 or say 900 



The estimate yield of good Ova is 150 gallons per 



annum, which at Q per gallon is . . 900 



But if only 100 gallons are obtained, and without 

 good management this is not improbable, the cost 

 rises to 9 per gallon, since 100 gallons at 9 

 per gallon is, . . . . . 900 



If the annual cost of water and the four ponds'are 

 found by taking 4 per cent, on the cost of construc- 

 tion, and adding 10 per cent, for renewals, which, as 

 the ponds require clean earth on the bottom and 

 sides every fifth or sixth season, is not too high a
