BLOODY POND.
In some of our old histories occasional mention is made of pools suddenly changing from water to blood, or putting on a sanguine aspect, which in those "muddy-evil" times was considered a prodigy portending wars and direful slaughter. A similar appearance was presented a short time ago in a pool at Snead's Green, Mathon, in this county, the surface of which was so closely covered with a film of crimson and vermilion as to present a most extraordinary appearance. The gentleman who first observed this sanguine aspect of the pond, not thinking much of portents or omens, thought that the rural wheelwright had been emptying some refuse red paint in the water, which had got dispersed over the pond. But on inquiry this was not the case, and botanical science was then called in to solve the mystery. In the mean time, more than a week having elapsed, the curious appearance was almost gone when the spot was visited by some members of the Malvern Club; but the clay on the margin of the pool displayed several patches of what looked very much like clotted blood, evidently the relics of what had been previously seen. On these being examined by Mr. E. Lees, who noticed the subject at a recent meeting of the Worcestershire Naturalists' Club, they were found to consist of innumerable minute globules containing a coloured fluid that oozed forth into a gelatinous mass, leaving the globules empty like small beads of glass; but so numerous and minute were they, that 6000 were contained within the superficial space of half a square inch. The bloody appearance was thus occasioned by the sudden fructification of an algoid plant, belonging probably to the genus Hæmatococcus, and allied to the singular production called Red Snow, though appearing in a different medium and under altered circumstances.
