other person, in the instances where the 

 information has no1 been furnished, can 

 determine b) a critical examination of 



the illustrations which have appeared in 

 Tin Gi CDE 10 X vn'KE, or that shall 

 appeal- in it. what kind of lens, the focal 

 length of the lens, the price of the lens 

 (S3. 00 or $50.00), which was used in 

 the making of the average respective 

 original negatives; the exceptions to this 

 rule being some instances when an an- 

 astigmat has been used wide open, and 

 when very rapid movement has heen 

 successfully arrested; hut in the case of 

 the latter it is not always safe to stake 

 too much on the correctness of the guess, 

 unless a confidential "tip" has been re- 

 ceived by the guesser from the man who 

 was behind the lens. 



The editor of The Guide to Nature 

 is to be congratulated because he is the 

 user of lenses of a higher grade than the 

 average of his subscribers and readers 

 can hope to afford. It is his privilege 

 to sing praises to his lenses and the 



makers thereof as often and as long as 

 In desires. If he feels it to be a duty, 

 let him do that duty well hut let him not 

 forget that it is also his duty, if he pro- 

 poses to teach photography, to show the 

 less fortunate of his pupils the way to 

 the best results within the limitations 

 of their respective equipments, and with- 

 out discriminating between the poorest 

 who can afford only a dollar outfit, ana 

 the most well-to-do to whom hundreds 

 of dollars will not be an obstacle to 

 separate them from the equipment they 

 desire. Let the Editor show his readers 

 how to become better workmen with 

 such tools as are within their purchas- 

 ing power: then, if the readers profit as 

 they ought by the instruction received, 

 they will be in positions to supply the 

 better pictures that are wanted. Twenty- 

 five per cent, may be in the lens ; seventy- 

 five per cent., and possibly more, of the 

 credit or the demerit is owing to the 

 worker who was behind the lens.
