184 EXPLORATION AND REGISTRATION WORK mittee from year to year. I have also been struck with the lack of practicability of many of these recommendations from my point of view—that is, of one having the success and progress of his society at heart. Such matters as "The Collection of Statistics concerning Trained Chemists employed in English Chemical Industries"; investigations concerning "The Resistance of Road Vehicles to Traction," or the "Consideration of means by which better practical effect can be given to the introduction of the Screw Gauge proposed by the Association in 1884," and the like, although subjects of professional importance, are but little adapted to enlist the co-operation of a body of amateur biologists, geologists, and archaeologists. It seems to me that the subjects most likely to prove attractive to the members of the greater number of our local Societies are those connected with such branches of science as are within the opportunities and abilities of amateur observers, and which at the same time are such as will arouse the enthusiasm and "county-patriotism" of the supporters of the Societies. It is difficult at all times to obtain a sufficient number of members to permit of the carrying out of the necessary work of the Societies (meetings, publica- tions, etc.), and it is still more arduous to collect funds for any piece of work supplemental to the routine business. I suggest that local Societies will best aid in their humble way the progress of science by confining their energies to the acknow- ledged three main objects of their existence—the minute study of the natural history and archaeology of the counties; in educational work of a propagandist character; and in assisting in the formation of well-planned local museums and scientific libraries in their own districts. All holding similar views will cordially approve of such pieces of work as the photographic survey of a county, or of the botanical survey advocated in a paper placed upon the agenda at the present meeting. And to be welcomed is the project for the preparation of a map index to prehistoric remains, so ably advo- cated by Mr. C. H. Read, F.S.A., at the Belfast meeting of this Committee.2 I should like to expatiate briefly upon these ideas, and, as I have no authority to speak for other counties, I will confine my remarks to Essex. 2 Abstracted in the last part of the Essex Naturalist ante pp. 123-6.
