(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 propriety 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 or 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 over 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.
