the cobweb-weaving theorists who do but spin webs from their own
intestines; but imitate the bees which both collect and fashion.' Re-
ference is usually made to recent publications only, since it is here
that assistance is most needed; these themselves will provide a guide
to the wisdom of the more distant past, for all historians stand upon
the shoulders of their predecessors. My citation of authorities will
itself express my gratitude to the historical world at large. To Mr.
H. G. Richardson, in particular, who read my manuscript in the
bits and pieces in which it was written in the night-watches of war,
I remain indebted for criticisms so searching that it would require
many books, and different books from this, to appraise them
properly.
