made separately, so that the stitch holes will not coincide 
when put together. Washing negatives is often difficult in 
travelling, but by having six soup-plates that will hold a 
Jr-pi ate without touching the bottom, and placing these 
in a row, filled with water, each negative may be passed 
through six waters, remaining in each during the time of one 
developing ; and this washing is almost always quite suffi¬ 
cient, while it requires but half-an-hour extra time to shift 
those in the plates successively after the developing is all 
done. 
It is very useful to take some paper upon which prints 
can be made on the spot for presentation to the natives 
(e.g., bromide or platinotype). In photographing groups, 
always focus before the natives are placed in position ; this 
can readily be done by placing an object on the spot where 
they will afterwards be made to stand. 
Other hints might perhaps be given, eg ., the obvious 
advantage in many ways of paper negatives over glass ; but 
on these points it will be better to cons alt the trade journals 
or apply to one of the leading firms, who will advise the 
amateur as to the materials best suited to the climate where 
they are to be used.
