LOCAL SCIENTIFIC SOCIETIES. 177 In this connection I would beg you to read the most fasci- nating and illuminating address delivered to one of our societies, the Yorkshire Naturalists' Union, by Mr. Lamplugh, when he was its President in 1906—an address which protested forcibly against the unhealthy distinction between amateur and pro- fessional, and put forward a plea for the need of the amateur spirit in scientific work. If I have succeeded in this address in making a practical suggestion that embodies the spirit of his appeal, I may hope in some measure to repay the debt that I owe to one who has always inspired me with the example of true and undivided allegiance to the call of pure science. It may well be that my views are visionary, and that those who know better than myself the constitution and the work of the Local Societies will pronounce the co-operation which I have suggested to be impracticable. Yet when I remember how many persons I have met in my own limited experience who were burning with the desire to do something in the way of scientific work, and only wanted encouragement and guidance, I feel sure that they are to be numbered by thousands. It is not enough to tell such people what they have to learn and bid them go away and learn it, or when they ask for work to give them words. Have we not in the Local Societies the agency which can get at these people and organise them as workers ? If not, where is such an agency to be found ? I think it a duty incumbent upon those of us who have had the opportunities, and have tasted the rare delight of scientific research, to lend a helping hand to those who desire to share both its toil and its treasure, but have not been able to reach these by the well-recognised path that we have ourselves pursued.
