It Is the only publication in America in which 

 dealers and collectors are sure of having their 

 notices placed in the hands of all working Nat- 

 uralists almost as soon as if done by addressing 

 each by letter— while In an ordinary monthly 

 publication there is natural delay of from 10 to 

 30 or more days. 



In the Natural Science News this delay will 

 be obviated. 



All copy must reach us at least three days 

 prior to date of issue in order to insure Inser- 

 tion in a given number. 



Florida Coast Shells 



at less than cost! 



Near the coast of Florida the mosqui- 

 tos and sand-flies are such a pest and an- 

 noyance to the Collector,during the sum 

 mer months, that we have concluded to 

 employ the most of our time, from now 

 until the first of October in the cleaning 

 and packing of Sea Shells. 



We therefore make you the following 

 offer: From now until October first we 

 will fill all small orders for Sea Shells at 

 very little more than the actual cost of 

 packing and postage. 



We will iill any order from ten cents 

 to $2, and give you a tiuer and larger 

 collection for the money than you ever 

 had before. 



We have large quantities of Florida 

 coast and river shells, and we take this 

 method of reducing our stock before the 

 autumn collecting begins. 



Unless otherwise ordered we will 

 send a general assortment, and each 

 purchaser, whether large or small, will 

 receive some line and rare shells. 



Send registered letter, currency or 

 stamps.

If so, learn to mount Birds, and then form classes and give instructions. 

 Any boy or girl of twelve or more years of age can learn to preserve and mount 

 Birds and Mammals inside of two days of practice, by the aid of my printed In- 

 structions, and can then give practical demonstrations and work before a class 

 of pupils. 



The pupils may be charged from Fifty Cents to several dollars each accord- 

 ing to the number of lessons required. It is better to give at least three lessons 

 or sittings, where the pupils can put up a bird each under the eye of the teacher, 

 but a single lesson is often highly satisfactory, for any man or boy can readily 

 comprehend the principles at once. 



There is a rare chance for energetic young and old people to learn a super- 

 ior yet simple process of mounting, and to take in some money by imparting 

 their knowledge to their acquaintances Scores of boys and girls are now giving 

 instruction by my process, and making money as well as improving themselves 

 as Superior Taxidermists. One boy has taught sixteen scholars. 



The prices are 75 cents for my complete Intsrnctions for mounting birds 

 mammals, fishes, game heads and game pieces for the walls, and one pound of 

 Compound. But by purchasing rive to twenty pounds at greatly reduced rates, 

 the Process is secured at a low price. There should be one instructor in every 

 town .
