PLEA FOR SYSTEMATIC ATTENTION TO AQUATIC BIOLOGY. 151 regard to them, and so perhaps lead to the recruiting of new workers for their special study. But it would do more than this, for it would incidentally sanction a longer delay at certain ponds, etc., than is usually considered necessary, and it is just this extra time at favourable places that is most needed by those who want to take the study of aquatic organisms seriously. Another very good way by which interest could be aroused and good work accomplished in regard to the matter under consideration would be for the Field Club to organize special Field-days solely or primarily for aquatic biology. In order to carry these through in proper scientific fashion it would be necessary for the organizers to provide at some convenient headquarters, tables, tanks, dishes, etc., as well as a few micro- scopes, so that as the material collected was brought in it could be suitably displayed. Many years ago, in 1909 in fact, this Club organized such a Field-day at the East London Water Works reservoirs at Walthamstow, and a most successful meeting it proved to be. If a series of such meetings could be held, say, in some of the private parks with lakes, in various parts of the county, they could hardly fail to be very attractive and of much scientific value. There is a still more ambitious way by which a Field Club, if it had the means, could promote aquatic biological research. I am thinking of the maintenance of a biological laboratory or station which, if it could be organized, would add lustre to the society and undoubtedly yield valuable scientific results. It is now more than twenty years since the idea of running a bio- logical station was first entertained by this Club. In the pamphlet entitled "The Essex Field Club : What it is ; what it has done (1880-1906) ; and what it wishes to do" (usually referred to as the "Red Book"), published in 1906, we read that "Another enterprise on which the Club desires to embark as soon as the necessary financial and other arrangements can be made is the establishment of a small station for biological research, preferably one which may be moved from one part of the county to another. This would form a centre and workshop for biological and faunistic research in connection with the Club's museums. Mr. William Cole has suggested that such an enter- prise might be—indeed ought to be—subsidized by the Local Authorities, such as the County Council (preferably through the
