SELL TO RESPONSIBLE DEALERS. 



The greatest trouble you have will not be to find a sale for your 

 specimens, but to get your money after you have sold them. I am sorry to 

 say that a vast number of purchasers will accept your shipments and never 

 pay you a cent. I know of only one way to avoid this difficulty and that is 

 to deal with responsible and honorable dealers, or else demand cash in advance, 

 or make your shipments C. O. D. by express, allowing privilege of examination. 



Dr. Barnes has given me full permission to refer to him when writing to 

 dealers, and as a slight return for his kindness I wish to state that he will 

 promptly pay for everything which he agrees to purchase. He is a millionaire 

 and has the finest private collection in America, therefore he is not in the 

 market for common species. It is quite likely, however,, that in each locality 

 there may be rare butterflies and moths which he would be pleased to obtain. 



I shall give the names of those who purchase lepidoptera and coleoptera 

 in future lessons of this course, without making any charge therefor, and am 

 anxious that purchasers should write me their desiderata. I want each sub- 

 scriber to learn to market his own material, but if each will send me a list of 

 what he has to sell I may frequently be able to obtain better prices for him 

 than he can himself, even though I deduct a fifty per cent commission. 



WANTED: CATOCALA EGGS. 



Dr. Barnes is at present in the market for all kinds of Catocala eggs, 

 takes 100 eggs of each species and pays at the rate of $1.00 per hundred. 

 Catocalas come readily to sugar and lay their eggs in paper bags. All you 

 have to do to secure eggs is to place the female in the ordinary paper bag used 

 by grocers, and to feed her with a piece of dried apple soaked in water to 

 which has been added a little honey. Evaporated apples will answer and 

 most any kind of fruit may be substituted if it is liberally sprinkled with sugar. 

 Catocalas will sometimes lay as many as a thousand eggs each. Before ship- 

 ping eggs to Mr. Barnes you will of course correspond with him and make 

 your own contract. I think that I can sell twelve hundred eggs of each 

 Pacific Coast species at one cent apiece or one dollar per hundred. The 

 species must be named and the eggs must be fertile. In shipping Catocala 

 eggs send the paper bag containing them and the mother moth. 



SETS OF LEPIDOPTERA. 



I have orders for sets of all moths and butterflies of the Pacific Coast, 

 and when I receive your lists I can write each one of you the price offered 

 for each species. I also have orders for nearly all species of butterflies and 

 moths in America, and so want the lists of every correspondent. Send me 

 samples of your moths and butterflies and I will name them and give you 

 estimates of prices. The time has arrived when those who wish to form private 

 collections can obtain specimens at reasonable prices. If all who have specimens 

 for sale will correspond with me it will be practical, in the near future, to offer 

 sets of nearly all American butterflies and moths at so low a figure that almost 

 any person of moderate means may purchase such a set. 



Now is the time to place orders for hibernating eggs, larvae and pupae. I 

 will purchase in lots of one thousand the cocoons of all the large, handsome 

 moths, and of many of the more brilliant species of medium size. These I 

 will retail out during the coming winter, at a slight advance on the purchase 

 price, to all correspondents who wish to buy. In this manner, for a nominal 

 sum, every person may experience the delight of seeing these wonderfully 

 beautiful creatures emerge from the pupae.
