keen powers of observation, a true love of nature and a bountiful 

 stock of that patience and persistence which all fishermen, 

 hunters and woodsmen so readily learn. So there is the material 

 of which to make admirable collectors. But first they must be 

 taught a few things; must be shown what I want and for what I 

 do not care. How shall I do this? Shall I tell the simple souls 

 that my desiderata are Lepidoptera, particularly the Heterocera, 

 that I am just now especially interested in the Bombycidae and the 

 Notodontians ? No, by so doing I should at once scare away my 

 neophytes and lose all chance of making them useful to me. I 

 dare not even ask them to capture " moths " for me. Few of 

 them apply that term to anything but the devouring insects which 

 eat their buffalo robes, their coonskin coats, the braided rugs 

 upon their floors, their flowering plants or garden vegetables. Be 

 the pest tineid, hemipter or coleopter, he is to the farmer in that 

 north country a "moth;" even the potato-bug and the Buffalo 

 beetle are "moths" in their vocabulary. But they know what 

 " millers " are. So throwing science to the wind — temporarily — 

 and casting aside all entomological traditions, I descend (ought I 

 not to say rise ?) to their level and boldly own myself a collector 

 of millers. But a new difficulty arises, I do not want all millers. 

 'I'hat is, 1 do not care to acquire all the specimens of one species 

 to be found in that locality. So after a hundred or more of some 

 common insect like Spilosoma ■7'i?-gi/iica are brought me 1 go a step 

 farther in my instructions and give orders that no more "white 

 millers" are to be gathered, liut I soon find that this again is too 

 broad and embraces too much. One of my country boys throws 

 aside as worthless a EucJuetcs collaris. Then I begin to show my 

 jiupils the more striking distinctions between the various white 

 moths. \'ery soon they know them apart and have their own 

 name for each, given because of some peculiarity of marking or 

 habit which they themselves discover or to which 1 call their 

 attention. 'I'hen Spilosoma 7'iri^i)iica becomes the "common white 

 miller," Spi/osofiia prima the " dirty-white miller," Jfyphantria 

 textor, the " littlest white miller." For Leucarctia acrcea I give 

 them Harris's old name of the " Saltmarsh miller," a term w^hich 

 is at once shortened and put into local dialect by my pupils and 

 thus becomes the "ma'sh miller." Last summer when absent 

 from the mountains 1 remembered the request made by an eminent 

 entomologist then interested in examination of the scent organs 

 of insects, that I would save him in alcohol specimens of Leucarctia 

 acrcea. So I wrote to one of my best collectors in the north
