A STONY PROBLEM.

The following queer query vexes the curiosity of a neighbour. On the edge of the grass lawn close to the gravel path are continually found small collections of pebbles of different sizes obviously taken from the path and deposited On the grass—but, by whom or- what-?-- and for what

reason ? Some of the pebbles are nearly an -inch long and the imprint in the gravel from which they were removed is clearly to be seen.- Every time the grass is cut these collections of pebbles, of course, have to be cleared off before the mower can be.used. 'The problem is not altogether new, but nobody has hitherto been able to suggest a satisfactory solution, 1Vorms have been accused, but would a worm be able or likely to lift a good sized- pebble out of its socket in gravel and deposit it on the grass two or three inches higher than the path ? Birds would hardly take the trouble, even if they could; to pick up the stones and put them all together in, little collections. Hedgehogs also have been accused.
