This time it meant slipping through unperceived as far as possible,
and in this we succeeded equally well. By good fortune we arrived
just before experiments commenced with the illuminating rockets.
Everybody's attention was centred on these and no one had time to
notice or observe what we were doing. We watched the preparations and
also the results, and having studied the routine and the geography of
the practice we were in the end able to help ourselves to some of the
rockets and the lighting composition, and with these we eventually
made off. Without delay we placed our treasures in the hands of a
trusty agent who transferred them at once to England.
