ger and then at the other, that here the 

 the foci of your eyes on the two fin- 

 gers are nearer together and the strain- 

 ing of your eyes from one to the other 

 is far less. If some one else will hold 

 up two fingers say six inches apart and 

 ten feet away from you, both fingers 

 will be in focus without any change. 

 Thus there has been secured perfect 

 depth by a long focus, but according to 

 the instruction books, the nearer the 

 fingers are to the eyes, the better will 

 both be seen at the same time, a state- 

 ment that plainly is a fallacy. 



Proof Positive of Anastigmat Value. 



To the Editor : Llano, Texas. 



About the enclosed picture being "a 



good argument along the line of our 



advocating high grade lenses" is not 

 really an argument" but an illustrated 

 fact. 



It is these "facts" that we wish to 

 draw the attention. Once this is ac- 

 complished the anastigmats are fully 

 competent of arguing the matter. 



The need of definite printed infor- 

 mation in our magazines and the mis- 

 placement of advertisements that are 

 primarily to blame. Excepting the 

 photographic magazines, lenses are sel- 

 dom advertised. 



"Convertible anastigmats" have 

 about as much meaning to the average 

 person as a "Convertible bond — such, 

 'U. S. refunding threes coupon' " — does 

 to a school child. 



I would suggest when printing an il- 

 lustration, the name and make of lens 

 be given below. This will give some 

 free advertising but persons asking for 

 information of that lens would cer- 

 tainly mention where the picture was 

 illustrated and eventually the publisher 

 would receive their advertising. 

 Yours very truly, 



Leslie L. Long.

Photographic Studies of a Water 

 Supply. 



Stamford, Connecticut. 

 To the Editor: 



The water supply of a town should 

 interest everybody since the public 

 health is so intimately associated with 

 potable water. 



I think that no other town in Con- 

 necticut has a better supply, either in 

 quality or quantity, than Stamford. 

 The analysis of the Stamford water is 

 as good as any that I have ever seen 

 and a great deal better than many. 

 Therefore, I think everybody should 

 be acquainted with the splendid plant 

 that we have, and to help a little bit, 

 I am sending you a few pictures taken 

 around the lake of The Stamford 

 Water Company.

 cement bridge which spans the ravine 

 at the outlet of the lake. 



No. 2 is a view of the ravine looking

No. 3 was taken from the top of the
