the abdomen being in this case also inserted in the water, 
After stirring the contents of the bucket with the hand, the 
water should be poured off and fresh supplicd several times 
in succession, until no trace of the milt can be seen, always 
taking care to keep the ova submerged. The spawn may 
then be moved to the hatching-ground or boxes; for the art 
ficial spawning-bed may be made in a ditch, dug for the pur 
pose, and paved, and supplied through pipes with water, as 
well as in boxes; but experiments have given the preference 
to boxes, as susceptible of forming thereby a stream more 
equal in flood, volume, and temperature. In the remoyal of 
the ova for a short distance, it is unimportant in what man- 
ner they are conveyed, so long as they are not much shaken. 
In transporting ova a great distance, it should be done in 
the winter or spring, placed in tanks lined with sponge and 
swamp-moss, With an aerating pump placed in it for frequent- 
ly moving the water, changing it, and exposing it to the air, 
Fecundated ova have been packed in moss by Seth Green and 
sent by mail a thousand miles, and then hatched with very 
small loss.
