circumstances, and in many cases with excellent 

 results, vide Mr. Andrews' successful ponds near 

 Guildford, where the adaptation of old water-cress 

 beds has proved most remunerative ; but under 

 ordinary conditions the ditch form gives the 

 largest return on the outlay, and (with the full 

 supply of water usually given to this class of 

 yearling ponds) most nearly resembles conditions 

 which abound in rivers and streams in all parts of 

 the country. Yearlings from these ponds, there- 

 fore, when transplanted to rivers, find conditions 

 not greatly at variance to those under which they 

 have been reared. With two-year-olds it is vastly 

 different, they have been reared in larger ponds, 

 where they enjoyed a wider range, and even if 

 the supply of water to their pond was propor- 

 tional to the supply usually allowed to yearling 

 ponds, yet the greater depth and breadth of 

 their pond so altered the amount of current as to 

 habituate the fish to comparatively still water. 

 Yearlings, therefore, have an advantage over two- 

 year-olds when transplanted to small streams or 

 rapid rivers. 



Yearlings have a further advantage over two- 

 year- o]ds at present rates for carriage, as, 

 roughly speaking, 2 tons 10 cwt. are required 

 to safely transport 1000 two-year-olds for twelve 

 hours, while 15 cwt. is amply sufficient for the 

 same number of yearlings on a similar journey.
