_Tent for Collodion._--As I have frequently benefited from the hints of
your correspondents, I in my turn hasten to communicate a very simple plan
I have contrived for a portable tent for the collodion process, in the hope
it may be found to answer with others as well as it has done with me: it is
as follows.
Round the legs of my camera stand (a tripod one) I have made a covering for
two of the sides, of a double lining of glazed yellow calico, with a few
loops at the foot to stake to the ground; the third side is made of thick
dark cloth, much wider and larger than to cover the side, which is fastened
at one leg of the stand to the calico. The other side is provided with
loops to fasten to corresponding buttons on the other leg, and by bending
on my knees I can easily pull the dark cloth over my head and back, fasten
the loops to the buttons, and then I can perfectly perform any manipulation
required, without the risk of any ray of white light entering; and
certainly nothing can be more _portable_.
The simplicity of the thing makes any farther description of it
unnecessary, to say nothing of your valuable space.
