66 THE ESSEX NATURALIST his more recent book, A Detective in Essex, and therein he acknowledged his debt to Watkins. I must confess to you that 25 years ago I was fascinated by the mass of apparent evidence which Watkins had accumulated in his countryside of the Welsh marches, and at first there seemed to me ample confirmation of his views in our own county of Essex. I said that his theory had been vigorously attacked and as vigorously championed, I fear with much emotion and little reason on either side. It is clearly an attractive theory to the lover of antiquity, but the desire to discover relatively simple geometrical or numerical relations is a perennial source of human error. You may remember the fantastic astronomical fallacy called "Bode's Law" in which the distances of the planets in the solar system were claimed to be related by a simple numerical series; to say nothing of the doctrines of "Numerology" and "Divination by Numbers" which have held sway over the minds of men for thousands of years. Also, much play has been made of the rectilinear alignments of places with names having simi- lar root-derivations, but the validity of the underlying theory has only limited acceptance. Some such hope of simplification has led Mr. Watkins and his disciples to go far beyond a statement of undoubted fact, namely, that many sites of antiquity can be grouped nearly in straight lines : it was felt necessary to apply the alignment theory to explain topographical features, to propound elaborate and esoteric reconstructions of ancient philosophies, to derive anew many of our place-names and to cast down the careful (but, I must confess, in my opinion, none too secure) structure of Place- name Philology. In this way discredit was brought upon observations which may not in themselves be lacking in value when unencumbered with fanciful theories. The lengths to which Watkins' amateur supporters were pre- pared to go is illustrated by a Communication from a Mr. E. M. Slader, of Chelmsford:— "This [Essex] is a country with very ancient earth- works, innumerable moats, mark stones, stocks, mounds, camps, etc. . . . Practically all the Essex churches lie in absolutely straight lines with outstanding sighting points at each end of the line; and almost every suggestive name
