RECREATION. 



that are not there when plates are set up 

 to dry. 



W. P. Brownell, Red Creek, N. Y. 



ANSWER. 



It would be difficult, without seeing the 

 spots, to properly state the cause. Send a 

 piece of one of the spotted negatives. I 

 suspect it may be due to roaches, or to 

 unequal drying. For roaches, whose 

 marks are holes eaten through the emul- 

 sion, place the drying rack in a pan half 

 filled with water. For uneven drying, try 

 putting the plates farther apart on the 

 rack to dry. Put 2 back to back in each 

 groove used, and let there be an inch, at 

 least, between faces. — Editor. 



SNAP SHOTS. 



Realistic photographs of the famous 

 Montana Bad Lands. 



Also of Mexican bull fights, showing 

 this tragic national pastime of our South- 

 ern neighbors in all its hideous details 

 from start to finish. 



I am making up a large club of sub- 

 scriptions to Recreation, and will send 

 to any person who will subscribe through 

 me, remitting $i for a year's subscription, 

 6 choice, unmounted prints, size 5x7, of 

 either series.

Some time ago I saw in Recreation 

 a reply to F. S. Jackson in which you said 

 that Nehring's copying ampliscope would 

 produce better nest pictures than the prints 

 forwarded by Mr. Jackson. In my expe- 

 rience the copying lens does not give suf- 

 ficient depth of focus, as one part of nest 

 will be in perfect focus and another part 

 entirely out. The portrait lens gives a 

 greater depth of focus, and seems better 

 adapted for this kind of work, while the 

 copying lens does perfect work in making 



copies.

Will you kindly inform me how to use 

 carbonette paper? Also give me a good 

 formula to use with it. 



Malven F. Jones, Birmingham, Ala. 



ANSWER. 



There is no paper on the market called 

 carbonette paper. It is common to call 

 prints on American aristo platino "carbon- 

 ettes," and I presume that is what you re- 

 fer to. Get a package of above mentioned 

 paper and you will find full directions for 

 making just such pictures as the profes- 

 sionals make if you have the negatives to 

 do it with. — Editor. 



answer. 

 Experiments in this direction generally 

 result in spoiling a good blue print. Green 

 may be had by making a saturated solution 

 of ferrous sulphate acidified with sulphuric 

 acid and then adding an equal bulk of 

 water. Immerse the print in this till green 

 tone arrives. I do not recall any formula 

 for changing blue to red — Editor. 



To clean negatives stained by silver, 

 wet a plug of cotton wool with a weak 

 solution of cyanide of potassium, rub gent- 

 ly all over the negative, using a little more 

 force on the stained parts. Well wash. 

 Dry on blotting paper. If necessary to re- 

 varnish, flood the plate once or twice with 

 methylated spirit. Let dry, and then var- 

 nish in the ordinary way. — Exchange. 



Will someone kindly give, through the 

 valuable pages of Recreation, the formula 

 for removing rust spots from negatives? 

 Also repeat the formula given some time 

 ago for making a focusing glass out of an 

 unexposed plate. This was claimed to be, 

 in some features, superior to ground glass.

Platinum prints in which the whites have 

 yellowed in consequence of the whole of 

 the iron salt not having been removed, 

 may be restored by immersing them in a 

 bath made by dissolving half an ounce of 

 sodium carbonate and 300 grains of chlo- 

 ride of lime in 8 ounces of water. — Ex- 

 change. 



A yearly subscription to Recreation is 

 one of the most practicable and useful 

 Christmas presents you could possibly give 

 a man or a boy who is interested in nature 

 study, fishing, hunting, or amateur pho- 

 tography. 



All boys instinctively love the woods. 

 Recreation teaches them to love and to 

 study the birds and the animals to be 

 found there. If you would have your son, 

 your brother, your husband, or your sweet- 

 heart interested in nature let him read 

 Recreation. It costs only $1 a year, arid 

 would make him happy 12 times in a year. 



For 10 subscriptions you can earn an 

 excellent camera; for 15 a better one; for 

 25 a still better. You can get these sub- 

 scriptions any winter evening. 



Can you give me any information in 

 regard to toning blue prints bright red, 

 and green? Ed. Myers, Washington, Pa.
