his volume records the "clay symposium" that featured the geology side of the Annual Meeting of the Institute at St. Louis, February 19-22, 1951. The symposium consisted of four sessions held under the joint sponsorship of the Geology Subdivision and the Industrial Minerals Division AIME and the Society of Economic Geologists. Its main purpose was to define or outline certain problems of clay and laterite genesis, and the papers herein, which were presented at the first three sessions, deal for the most part with individual deposits or special problems. The fourth session was a seminar concerned almost wholly with a discussion of "problems." The discussion follows the papers in the volume. The clay symposium was not the work of an appointed committee. It was thought up and inspired by John J. Collins, who so ably supervised and co- ordinated the mining, geology, and geophysics program for the 1950 annual meeting of the Institute. After requesting Dr. A. F. Frederickson to get material together on clay and laterites for the St. Louis meeting, Mr. Collins visited Dr. Frederickson and discussed this project with him in greater detail. By that time their interest and enthusiasm had spread to others in the field. The Geology Subdivision, the Industrial Minerals Division, and the Society of Economic Geologists by common consent turned over the organization of the program to Dr. Frederickson. Mr. Collins continued in active touch with Dr. Frederickson and gave him every assistance. Dr. E. C. Harder and Dr. W. D. Keller read all the material comprising the symposium, and their comment was made available to Dr. Frederickson, who did much to put papers and discussion in final shape for publication. To the Karl Eilers Memorial Fund--one of the Funds that enables the Institute to publish books of this kind, to the authors of the various papers, to the contributors to the discussion, and to Messrs. Collins and Frederickson the Institute and readers of this book are indebted.

Some years ago the open Hearth Committee of the Institute reached the conclusion that the reading of "set" papers tended to preclude the specific and detailed discussion of specialized problems of current interest to those operating steel plants. As an innovation the Committee distributed in advance of the meeting in May, 1927, a questionnaire containing a list of 27 topics involving operating problems. The subsequent discussion of the questions, participated in by 37 members, was a conspicuous success. Semiannual meetings have been held since; and at the conference of November, 1929, at Chicago, 131 men were present and the minutes comprised a book of 133 printed pages, thereby, indicating the growing value of the conference in the eyes of both the metallurgists themselves and the companies that employed them. With this example in mind, the Directors felt that definite advantages would accrue to a similar conference to be participated in by smelter officials and metallurgists engaged in the operation of copper reverberatory furnaces. The settlement of the Carson litigation, which for several years had virtually stopped public discussion of reverberatory practice, offered an opportune time for launching the scheme. Although the Conference may become largely self-financing in the future, some funds were regarded as necessary to conduct the first meeting. The members of the Rocky Mountain Income Committee, in view of the fact that copper smelting was essentially an activity of the Rocky Mountain area, recommended the project be, in effect, underwritten by the Fund, and the directors approved an appropriation for this purpose. Invitations were extended to high executives of the various-companies interested to send representatives to an initial meeting to be held at Salt Lake City, May 26-27. The response was enthusiastic. Twenty-three metallurgists representing 12 different plants were present to discuss the comprehensive-program relating to construction and operating phases of reverberatory smelting. It was understood that the record was not to be included in the regular publications of the Institute but that it would be prepared for private distribution among the participants and the officials of their companies. That the exchange of views and experience was no less instructive and stimulating than it was frank, full and informal is indicated by the following transcript of the minutes of the meeting.

When the Seeley W. Mudd Memorial Fund was established in. 1929 the donors mentioned certain types of projects to which preference might be given in selecting those to he financed by the income from the Fund. One suggestion. was that the projects "be of particular benefit to young engineers." This modest little book meets this specification most aptly. It seeks to guide the engineer-particularly the young one-with the least loss of time and effort to the most convenient source of authentic information regarding any topic in which he may at the moment be interested. Knowing the best place to find the literature on a subject is almost as valuable-and far more practicable-than maintaining a library of one's own large enough to provide the information.
