The Mansfield Automatic Water-finder

Abstract

WITH reference to Mr. A. A. Campbell Swinton's letter in regard to Mansfield's water-finder, which appears in NATURE of October 14, it may be of interest to state that I made inquiries from Messrs. Mansfield and Co. in May, 1908, asking for the names of the “leading scientists and engineers” who, as they stated, “vouched for the successful application of the invention”; they did not send me any names, but allowed a friend of mine in Liverpool to call to see the documents. One was from an architect in Liverpool, another from a firm of well-borers, and there were some foreign ones, but none were produced that were signed by persons whom I should describe as “leading scientists and engineers.”
