THE GOLDFISH AND ITS CULTURE. 61 
At the expiration of about a week from the time the first young 
were placed in the nursery, the strongest are taken out in the follow- 
ing manner: A candy jar is filled half-full of water from the nursery, 
and set right in the center of the bed and resting upon the bottom of 
it. The largest fish are now slowly and gently caught with a 
small dip-net, one at a time, and immediately in the same careful 
manner placed in the jar, counting them as they are transferred. It 
is not advisable to place more than fifty of these little fish in the jar 
while removing them, neither should they remain in it longer than is 
necessary to transfer them into the rearing ponds, the whole time 
consumed in the operation should not exceed a few minutes. 
The morning is the proper time of day to perform this operation, 
as the temperature of the water in the various ponds is at that time 
most uniform. If the manipulation is done at any other period of 
the day, it becomes necessary to gradually equalize the temperature, 
as a difference of a few degrees only would prove fatal to the tender 
young if suddenly removed from one water to another.
