Caution to readers -- this is a serious case for the defense, not a book dealing with hocus pocus. And yet to the vast majority of Kenneth Roberts' admirers, the subject of ""dowsing""(known to many as water witching) is on a par with the ouija board. Not so for Mr. Roberts, who undertakes to present meticulously documented cases to prove that the miracle of the dowsing rod may well be another opening door to appreciation of the existence of an unknown power. Henry Gross is a convincing figure, as his 100% record of success in locating water where others failed, would indicate. Kenneth Roberts has found him infallible. His fame (at the start local to his Maine habitat) began to spread. Even the sceptics who came to jeer remained to praise. The book holds closely to the subject; this is not a regional book about a colorful downeaster. It is a book about Henry Gross and his strange power. At a distance of 800 miles, from Kennebunkport, Maine, to Bermuda, Henry Gross indicated where water would be found, at what depth, in what quantity. And he was right, as the record of the diggings proved. The book is filled with experiments and scientific findings, witnessed by man of unimpeachable veracity. That Gross does not stand alone is evidenced by the inclusion of chapters by the other rod wielders,- a French scientist, an English dowser. Roberts does not claim that all dowsers are equally gifted; in fact he suggests that in this- as in other little understood realms of extra sensory perception- there are amateurs and fakers.... A book off the beaten path, which- under Roberts' name- will be read by many. Don't overlook it.
