1, 13s. 4d. per thousand two year-olds but 

 the saving in cost of railway charges for carriage 

 is in each instance much greater. In conclusion, 

 we are of opinion that, while Fishery Boards 

 working on this large scale may, under favourable 

 circumstances, raise yearlings at 6 per thousand 

 all told, large and small, it would not pay them 

 to place their surplus stock on the market below 

 10 per thousand, and if they only rear 50,000 

 or 60,000 yearlings annually, it is open to doubt 

 whether these yearlings will not cost close on 10 

 per thousand in the ponds before handling at all. 

 In the above calculations all profit in any of the 

 stages has been neglected. If in the table (page 

 44) we substitute the price of 30 gallons of Ova 

 grown into three-month-old fry for the bare cal- 

 culation cost. The table will stand thus : 



The equivalent of 30 gallons of Ova, viz., 120 



boxes of fry at 5 per box, .... 600 



Kent, repairs and renewals, .... 250 



Cost of food, 80 



Attendance, 78 



Cost of equivalent of 30 gallons of Ova in year- 

 lings, say from 140,000 to 200,000, . , 1008 



or 33, 12s. per gallon, or from 5, Os. lOd. to 

 7, 4s. per thousand. This calculation is made 

 for the convenience of Boards and Associations, 

 who prefer to purchase their fry instead of incurr- 

 ing the expense of a large hatching house. And
