cxxx Journal of Proceedings. greater part of it has become covered with vegetation. I append a list of plants (fifty in number), which made their appearance on the mud, as soon as its surface had become firm enough to walk upon. A part of the mud was removed three years ago, and the whole was taken out and carried away ten years ago. In the winter a stream is occasionally turned into the pond. There were several other plants in too young a stage to be de- termined ; and what was surprising, an absence of some of the commonest plants, charlock (Sinapis arvensis. Linn.), for instance, which is one of the most plentiful weeds, the seeds of which must have been deposited in profusion in the ditches which supply the stream in winter, which occasionally debouches into the pool. The seed of this plant is so exceedingly tenacious of vitality, that a farmer once told me he had twelve acres, to use his own expression, " so poisoned with it," that he determined to put it down as pasture for sheep feed ; after eleven years, he ploughed this field up again, and the weed came up as thick as ever it had been. I remember many years ago, in opening a Saxon 800 to 1,000 years old barrow, in what had been the stomach of its incum- bent, there was a quantity of small seeds, of which Professor Henslow took possession. I asked him, three years after, if he had tested, or discovered any vitality in them ; he said, " If you pay a visit to the Botanic Gardens at Cambridge you will see that their produce is a plenti- ful crop of wild raspberries." We hear of wheat growing after being enclosed in the hand of an Egyptian mummy, but life existing in seeds for 3,000 years requires a good stretch of belief. In earth thrown out from a depth in digging a well, generally some plant makes its appearance which is not common, or has not been seen before in the neighbourhood, and it is not impro- bable that the seeds of the plant Erucastrum inodorum, for the discovery of which Mr. Joshua Clarke obtained the gold medal of the Royal Horticultural Society, were thrown out with the soil in making the deep railway cutting at Wenden.
