A MAN THAT GOT MAD 



Two Years Ago, and Discontinued His Subscription to 



THE GUIDE TO NATURE 



came last week from a distant city to visit ArcAdiA, because, he said, he 

 had reached a new point of view by reading 



"The Spirit of Nature Study" 



by Edward F. Bigelow 



He said that the book made many things clear to him, and gave him a 

 clearer understanding of several phases of nature study, and of the meaning 

 of this magazine. Perhaps the visit also aided. You can get the book 

 postpaid for One Dollar, and visit ArcAdiA free.

Noslip Printing Mask 



(PATENTED) 



For Printing Film Negatives 



The Noslip Printing Mask is the latest im- 

 provement in printing masks. It does away 

 entirely with_the_slipping of the negative 

 when placing the paper in position in the 

 printing frame which frequently occurs with 

 all of the old style masks. It does away with 

 all bad and ill-shaped edges, leaving a neat, 

 even, white border all around the print. This mask has pockets in the four corners into which 

 the film is slipped. Full directions with each set of masks. Each set consists of three masks, 

 one for post cards, and one each with oval and square opening the size of the negative film.
