THE CAMERA

following from Mr. J. H. Jost of Hali- 

 fax, Canada, will not only amuse but 

 edify our readers. 



"Kindly send me particulars regard- 

 ing nature photographs. Might say 

 that the fuzzy kind are not in my line 

 and never were. I have no use for 

 them. I see no art in them. One 

 may send a painfully sharp print 

 to the photo-engraver and ask him to 



make a fuzzy out-of-focus half tone, 

 and when the picture is reproduced the 

 photographer is an "artist" for making 

 such an atmospheric picture which the 

 photo-engraver manipulated according 

 to orders. And this is art ! I regret to 

 say that I am not an artist in their esti- 

 mation nor will I ever be. I would like 

 to write a chapter or two on this sub- 

 ject but space forbids right here."

Some Uncommon Bronx Minerals.

Specimens of minerals may be inter- 

 esting for various reasons, the com- 

 monest of which are probably beauty 

 and rarity. It is the beautifully crys- 

 tallized and colored specimens that 

 usually attract the most attention ; 

 though of much greater interest to the 

 collector and enthusiast are those of 

 minerals that are rarely found in the 

 region in which they were collected, 

 while of superlative interest are those 

 specimens which exhibit minerals never 

 before found there. Of the minerals 

 here mentioned, all owe their chief in- 

 terest, apart from the personal associa- 

 tions, to their comparative rarity, 

 though some possess also the charm of 

 being well crystallized. 



One of the minerals not commonly 

 met with is chabazite, azeolite. Though 

 reported from other parts of the Bor- 

 ough, I have found it at but one locality, 

 in some hornblende schist at 175th St., 

 just east of Third Ave. The mineral, 

 as found there, is flesh-red in color and 

 well crystallized in rhombohedrons that 

 resemble cubes. While several good 

 specimens were found, the mineral was 

 not abundant. 



Another iare mineral, and one that i 

 seems to be less common than the pre- 

 ceding, is green copper carbonate or 

 malachite. This, too, was found at but 

 one place, near West Farms, in the 

 neighborhood of 174th St. and South- 

 ern Boulevard, where it occurred as a 

 thin coating on a mass of hornblend 

 schist, which had been brought there, 

 probably, from a nearby excavation 

 whose whereabouts I was unable to 

 determine. Though thin, its color is 

 the characteristic malachite-green 

 which is, however, not uniform, some 

 parts being darker than others. The 

 incrustation covers about a square inch. 



In the limestones, good crystals of 

 rutile in which the termina are very 

 well shown are occasionally found. 

 This mineral is a compound of titanium 

 and oxygen and is characterized by a 

 peculiar steely, or as it is more techni- 

 cally called, subadamantine luster. In 

 certain positions it appears very dark, 

 almost black, in others reddish, partic- 

 ularly along broken edges, which are 

 much lighter in color than the other 

 portions. The best specimens were 

 found along the Concourse in the 

 neighborhood of 174th St. Some other 

 specimens, I believe, were found be- 

 tween Washington and Third Avenues,
