80 FISH CULTURE—MELLISH. 
while in the work at the older institution in Neweastle, Ontario, 
and afterwards while in charge of the hatcheries at Gaspe 
and Miramichi, has enabled him to introduce into the Bedford 
establishment the most improved and serviceable appliances for 
prosecuting the work on a large scale. Among these appliances 
which are as yet only used in his establishment, but which will 
shortly be introduced into the others, are Ist, a set of filterers for 
preventing the foul sediment from coming in contact with the 
ova, and thereby injuring them ; 2nd, a new description of tray 
or hatching grill, upon which the ova are placed during the sea- 
son of incubation ; these trays are of the ordinary earthenware, 
covered with a thin salt glazing, and were introduced to prevent 
the possibility of any chemical action which might injure 
the young fish, between the iron and sulphur contained in 
the water and the zine of the trays previously introduced by 
Mr. Samuel Wilmot, and which up to this date were the 
only trays used; 3rd, a simple but most serviceable escape or 
overflow pipe, which will permit any required quantity of 
water to pass through the hatchery trough, while no young 
fish can possibly escape. Aided by these improvements, Mr. 
A. B. Wilmot has been enabled to achieve a degree of suc- 
cess comparatively greater than that attained in any of the older 
establishments. As it was impossible to obtain from the Sack- 
ville River a sufficient number of the parent fish, from which to 
obtain a full stock of ova, recourse was had to some remote 
rivers of this province, principally River Philip in Cumberland 
county, West River in Pictou county, and the Annapolis and 
Musquodoboit Rivers. Those rivers producing the largest salmon 
were chosen in preference to the others, the object being to re- 
stock the depleted rivers with a larger run of fish than formerly 
frequented them. At convenient points auxiliary establishments 
or reception tanks’ and spawning sheds are erected, in which 
to confine the salmon and perform the delicate and important 
work of manipulating. The result of Mr. Wilmot’s labours for 
the three years this‘ establishment has been in operation, has 
been the hatching and distributing among thirty-five rivers of 
this Province, the large number of 3,000,000 Salmon, 160,000
