Shell-traps were always laid about the grass, consisting of slates, under which there would generally be found a various crop of sorts. I have now two glass cases containing all the shells, land and fresh-water, of Hitcham, mounted by the Professor himself. A reward was offered for every specimen of a Helix with the shell reversed. They are very rare, but one was brought by a little boy who discovered it, for he found he was unable to get his thumb into the opening the right way when playing at "conquerors." So he got the only sixpence earned in twenty-three years that the Professor was incumbent of Hitcham. The collection of butterflies was always being added to; now and then a rare one would appear at Hitcham, as, e.g. the Camberwell Beauty. The Professor was walking in the Rectory garden with the late Judge Eagle, of Bury St Edmunds, when one settled on a wall. Mr Eagle stood sentry while the Professor ran indoors for his net. It need hardly be added that the specimen still rests in the collection, which passed into the possession of his son-in-law, the late Sir J. D. Hooker, F.R.S., etc. I cannot do better than conclude with my uncle's words at the end of his _Memoir_:--"When a good man dies the world does not cease to benefit from those labours of love which he undertook for his fellow men. Though personally removed from them his example remains; his voice too, is still heard in the lessons left to be handed down to those who come after him. The influences of Professor Henslow's teaching have been felt in other places than those in which he himself taught, they have borne fruit far beyond the obscure neighbourhood in which he first sowed the good seed, and who shall say to what further results they may not grow in years to come, bringing honour to his memory, and what is far more, glory to God? '_'A word spoken in due season, how good is it!_'" FOOTNOTES: [96] _Memoir of the Rev. John Stevens Henslow, M.A., F.L.S., F.G.S., F.C.P.S._ (J. Van Voorst, 1862). [97] _Memoir_, pp. 17 ff.
