of the toning bath; (2) by hypo in the wash- 
ing water or in the toning bath; or (3) by 
the print coming in contact with an ex- 
posed piece of zinc or other metal in the 
washing tank. These stains may often be re- 
moved by a little alum solution brushed 
over them. Sometimes, however, this meth- 
od fails, when the following will be a certain 
cure. It is always best, however, to try the 
alum solution at first, as soon as possible, 
for it prevents the stain from spreading. 
Dissolve 2 ounces of calcium chloride in 20 
to 30 ounces of water, and at the same time 
dissolve 4 ounces of potassium carbonate 
in 10 to 20 ounces of water. Add the 2 to- 
gether, boil and filter through double filter 
paper. Place the print, or prints, in this so- 
lution, when the stains will depart. After- 
ward wash well, and place prints in alum so- 
lution to harden the gelatine. Wash again 
and dry. 

Editor RECREATION: 
For the past 2 years I have been a con- 
stant reader of RECREATION and have fol- 
lowed its career with keen interest. Being 
a lover of nature and a true sportsman, in 
all the term implies, I am anxious to see 
this magazine fill the sphere for which it 
only is fitted. JI am anxious to see the 
photographic department enlarged, but I 
fully appreciate that this can only come 
about by the constant co-operation of the 
readers of the magazine. They must con- 
tribute their ideas and experiences. The 
field for the exchange of opinions is a vast 
one, and all should share in its benefits. 
RECREATION should become a recognized 
authority on amateur photography, as it 
is in it’s other lines. 
Every little helps, I am going to append 
a formula for developing plates exposed 
under all conditions. I have used this de- 
veloper on plates exposed many hours, and 
on “snaps” given, but I-200 part of a sec- 
ond, and have produced results most excel- 
lent in both cases. 
Mr. Shumaker, in a recent issue, asks 
for a formula, or directions for developing 
snap shots. If he will make up this de- 
veloper and use it as I say, he will find 
it in every way all he wants. The formula 
is as follows:

gredient until the other is fully dissolved. 
Then add the suiphite of soda, and when 
that is fully dissolved add the yellow prus- 
siate of potash. This solution should be | 
filtered and kept thoroughly stoppered, in 
a glass stoppered bottle. Corks spoil most 
all fluid solutions used in photography.

This solution is of course easily made, 
but must not be filtered. 
To develop a snap shot, on saya4xs | 
plate, take 2 graduates, and into one of 
them pour 2 ounces of No. 1. Into the 
other pour one drachm of No. 2. Flood 
the plate with the No. 1 solution and allow 
it to soak well into the film. Pour it back 
again in the graduate and add to it the 
one drachm of No. 2. Pour this combined 
solution on the plate and develop in the 
usual way. The image does not appear un- 
til the combined solution is poured over the 
plate. The shorter time the plate has been 
exposed, the longer it should soak in the 
No. 1 solution. Ifa plate has had plenty 
of time and requires no forcing at all, the 
2 solutions may be mixed, in the first in- 
stance, and flowed over the plate as usual 
with the ordinary developers. The object 
of flooding with the No. 1 solution first, 
is to prepare the film for the aggressive 
action of No. 2. 
By using this developer in this manner, 
a deal of latitude can not only be given in 
the exposure, but it also allows of as much 
latitude in the developing’ a truly great 
boon to the average amateur. The quan- 
tity of No. 2 solution can of course be 
varied to suit the case at hand, and ‘t 
can be modified in the manoeuvering so as 
to produce any result desired. Clear, cold 
gray negatives, to heavy, dense black ones 
can be obtained at pleasure. In fact, any 
quality desired can be obtained from it, as 
1 know by experience. I also have used it: 
by mixing the 2 solutions first and adding 
a little water, for the development of lan- 
tern slides and bromide papers, and have 
produced excellent results with it. In 
every way, it is an “universal developer.”
