THE AQUARIUM, JANUARY, 1897. 



Now is the time to pay your sub- 

 scription for The Aquaeium. This 

 should always be attended to promptly, 

 bearing in mind that this little maga- 

 zine is published in the interest of a 

 good cause — your recreation. 



When regulating the light for your 

 aquarium or for your plants by means 

 of the window shades, you should pay 

 as much attention to this work in 

 dark, rainy weather, for the welfare of 

 your collection, as you do in sunny 

 weather, for the benefit of your carpet. 

 In sunny weather the shades may be 

 down, but in cloudy weather supply all 

 the daylight you possibly can. 



At least once every week you should 

 wipe the inside glass of your tank with 

 the wiper or a flat sponge tied to the 

 end of a flat stick. This precaution 

 properly attended to in the early sjDring 

 will prevent much annoyance later on. 



The best of all-glass tanks, although 

 they are " made in Germany," are not 

 as desirable for an aquarium as are the 

 rectangular metal-frame tanks with 

 select sheet or plate glass. The all- 

 glass tanks sold in the American mar- 

 ket for aquarium purposes, not having 

 been designed for this purpose, are sel- 

 dom of entirely clear glass, or without 

 defects of some kind. Entirely fault- 

 less tanks are made with polished sides; 

 these are intended for scientific pur- 

 poses and come very high. 



The greatest advantage claimed by 

 some people for these tanks is their 

 being made in one piece, which pre- 

 vents leaks. So it does. But a well- 

 made metal-frame aquarium never 

 leaks, so then, where is the advantage ? 

 If one of these all-glass tanks is in- 

 jured by accident, the entire tank is 

 gone, while when one glass is injured 

 in a frame tank, the injured part only 

 is lost, and this is easily replaced at 

 small expense. 



So we see that the condition which 

 is claimed as their greatest advantage, 

 is really their weakness. 



It requires money to publish a paper 

 and the circulation of a paper, of the 

 nature of the Aquarium, is limited. 

 You should, therefore, assist the pul)- 

 lisher as much as you can by securing 

 new subscribers and by renewing your 

 own promptly. 



Copies on stiff paper of the compara- 

 tive thermometer scale and comparative 

 inch and centimetre measure, printed 

 on another page, may be had on applica- 

 tion for a two cent stamp. 



The Aquarium assists you to in- 

 struct your children, helps to entertain 

 your friends and supplies to yourself 

 many hours of wholesome recreation. 

 For all this you should be willing to 

 pay as cheerfully as you do for a lecture, 

 concert or theatre ticket, which is com- 

 paratively much more expensive. 



We are in receipt of many com- 

 munications, especially jiostal cards, 

 the signatures of which we are unable 

 to make out. Want of attention 

 towards your communication may be 

 traced to this cause. You should sign 

 your name and address plainly.
