KIRKUS REVIEW

For those who have never heard of the Daniel Johnson Dam, it is the ""Pride of Quebec."" Undoubtedly. It is the world's ""highest multiple-arch concrete dam."" A totem to technology. But only a structural engineer could wade through this report. ""Manic's batch plant was a semiautomatic unit. The operator had a console which showed on a dial precisely what was going into each batch. For instance, to make a typical cubic yard, the dial reads zero; at the push of a button an air valve opens a gate and 3-6-inch aggregate falls into a hopper suspended so that a scale records the weight of its contents. When the scale dial reads 900 pounds, that gate closes and the gate under the 1(apple)- to 3-inch aggregate opens to dump 695 pounds of that size from the bin high overhead."" And so it goes. . . in a book that should only have been issued to those contemplating other dams in other places. We are just contemplating damns.
