     These files are colour scans of stereo photographs. 
All are presented in the cross-viewing format in order to be seen
on a colour monitor without optical aids.  To view a picture in
stereo, display it in its entirety and cross your eyes so that the
two halves of the image merge.  It is often helpful to over-cross
the eyes and let them relax somewhat until the scenes merge into a
stereo view.  Concentrate your attention on some prominent feature
of the scene, preferably in the distance, and get these to merge
first.  Once full merging takes place you will be able to move your
eyes around the scene at will.

     Don't be discouraged if you don't achieve the stereo effect
easily.  Some people have more trouble than others, but cross-
viewing is a skill than nearly everyone can learn.  If you are new
to the technique, don't overdo it.  Crossing the eyes tires muscles
that are not used to being treated that way.  Take frequent breaks
until you have built up muscle strength through this unusual
exercise.  (You will not hurt your eyes in the process.)
