young fishes. 
Heating arrangements other than a portable odorless oil stove or a 
small coal stove are not required, and these need only be employed in the 
most inclement weather; experience having proven that goldfishes thrive 
best when not kept in too warm temperature, 45° to 50° F. being better 
than higher, and if no rapid changes take place those just above freezing 
are not injurious, except to the transparently-scaled Chinese breeds developed 
in a warmclimate. Warmer water is necessary during the breeding season. 
The sash of the greenhouse should be arranged to open in the direc-
