2. " Salmon Acclimatization in New Zealand," by W. Lauder Lindsay, 

 M.D., F.R.S.E., Hon. Mem. N.Z. Inst. 



The introductory portion of this paper was read by Mr Webb. 



(abstract.) 



The author began by giving a history of his connection with the two 

 experiments of 1867 and 1873. He then proceeded to enforce the importance 

 of shortness of interval between the time of collecting the ova and their 

 deposition in the breeding pond, and the necessity for speediness of transport, 

 which can be obtained by substituting steamers for ordinary sailing ships ; 

 and, for the same reason, he urged the propi-iety of selecting California as 

 the source of supply instead of Britain. He dwelt on the advisability of 

 making a variety of experiments on means of preservation of ova, which would 

 be calculated to secure greater certainty of result at a less expenditure than 

 package in ice-houses on board ship ; on the necessity for skilled supervision 

 during the collection, transport, and hatching of ova ; and on the importance 

 of making due preparation for their reception in ponds constructed on suitable 

 sites, and supervised by skilled superintendents. The possibility of transporting 

 live parr Qr smolt, or even mature salmon, on short voyages, if placed in 

 swing tanks or decked wells, was also suggested. The necessity for swinging 

 the ova-boxes on gimbals, and so fixing their supports as to prevent upsets or 

 violent jolts, was pointed out, as well as the importance of keeping the ova 

 cool throughout the voyage by ice-cooling or refrigeration of the water or 

 other substances in which they are imbedded ; and the author finished by 

 urging the propriety of extending the shipments ovei- a series of years, so as to 

 guard against any chance of failure. In the paper was interspersed a large 

 mass of correspondence with many gentlemen, including some of the most 

 eminent living authorities on the subject of salmon-culture.
