EDWARD F. Bigelow, Arcadia, 

 Sound Beach, Connecticut, desires 

 for the "Nature and Science" Depart- 

 ment of the "St. Nicholas" Magazine 

 (New York), photographs of interesting 

 inventions, and of natural objects that 

 are novel, instructive or especially 

 beautiful. He particularly desires 

 photographs of machines or mechanical 

 appliances of interest to the readers of 

 "St. Nicholas". They may be mounted 

 or not, of any size and on any kind of 

 paper. The only requirements are that 

 they shall clearly show something worth 

 showing, and be interesting or instructive. 

 Do not send "snap shots" of scenery 

 that can be equalled for beauty and for 

 general interest in almost any part of 

 the earth. Pay will be at the usual 

 magazine rates, and will vary with the 

 interest and the novelty. A small photo- 

 graph may be more valuable than a big 

 one. 



"The Guide to Nature", Arcadia, 

 Sound Beach, Connecticut, is a magazine 

 for adults, and has a definite purpose. 

 It is published by an association of 

 students and lovers of nature — not for 

 pecuniary gain, but to be helpful. Its 

 department, "The Camera," is conducted 

 by enthusiastic camerists, each of whom, 

 as in a camera society, desires to help 

 all his associates and colleagues. Editor, 

 associates and contributors are paid by 

 the satisfaction of benefitting others. 

 There is no better remuneration. All 

 income is devoted directly to the inter- 

 ests and improvements of the magazine. 

 You are invited to cooperate. Sub- 

 scription; $1.00 a year. Single copy: 10c. 



How to Construct a Breeding Tank 

 of Wood. 



w 



H. K. LIPPINCOTT, Philadelphia. 



ITH spring approaching, the 

 thoughts of the amateur fish 

 breeder naturally turn to the spawning 

 season. Few are fortunate enough to 

 possess greenhouses with cement tanks 

 where this operation may take place, 

 hence it behooves the rest of us to look 

 about for suitable receptacles for our 

 purpose. This generally results in a 

 miscellaneous collection of tubs, pots, 

 pans and jars that lend anything but an 

 artistic touch to the garden and lawn. 

 Too, this motley collection of non- 

 descript utencils usually excites strenu- 

 ous objections from the feminine side of 

 the house. The aquarist has enough 

 trouble that cannot be avoided, so it is 

 best to side-step this issue by adopting 

 neat and uniform tanks. 



Cypress lends itself admirably to our 

 purpose, being a tree whose habitat is in 

 very wet places. This wood resists the 

 action of water far better than others, 

 is inexpensive — costing about six 

 cents per board foot — and being a soft 

 wood is easy to work. The construction 

 is exceedingly simple as shown by the
