PROBLEMS OF FISH AND FISHING

 inches (weighing 8.34 pounds) being a gallon. 



Demonstration a(inaria arc usually l>uilt into iIk- w;ills ><> as to !"• 

 lighted from alxjve and \i<'\ve<l through tiu; glass from inside tin- 

 room. This arrangement can be imitated l)y setting the acpiaria on 

 suitable supports just outside the windows, on the wandow sills, darken- 

 ing the outer glass (or making the ends and outer sides of slate). 



When we begin to realize the value of aquatic biology, we shall build 

 our aquaria into the basement walls, and then, by proper placing and 

 grading of the building, we can have abundance of room for either still- 

 water or running-water aquaria, under conditions as normal as tliose of 

 natural ponds and streams, with which to study all manner of ])rob- 

 lems. If the aquaria were figured into the original plans, they might 

 cost nothing and the basement walls might be even less exi^ensiv.' 

 than the usual solid construction of stone or brick. 



Our commissioner of fisheries says ^ : ''This is a wide ti«dd ; I do 

 not know of any more promising field in the government service than 

 in the culture of fish. The pos.sibilitics of nniking new discoveries, 

 especially in the line of intensive breeding and selectivj- breeding, an- 

 almo.st inexhaustible. I would expect that a tremendous boom to the 

 fi.sh industry of the entire country woidd be given by a lisheries .schoc.l 

 such as this if established here." 



The still-water aquarium is the (»nly kind recommended for ordi- 

 naiy school use; running water is not at all necessary for most tisiies.
