INSTINCT OF SPIDERS.
(For the Mirror.)
The following fact is copied from a French work entitled Archives sur Anatomie:—"A small spider had spread its net between two neighbouring trees, at the height of about nine feet. The three principal points, to which the supporting threads were attached, formed here as they usually do, an equilateral triangle. One thread was attached above to each of the trees, and the web hung from the middle of it. To procure a third point of attachment, the spider had suspended a small stone to one end of a thread; and the stone being heavier than the spider itself, served in place of the lower fixed point, and held the web extended. The little pebble was five feet from the earth." The whole was observed, and is described by Professor Weber, of Leipsig.

COBBETT'S CORN.
(Concluded from page 79.)
The first operation on the grown plants is that of topping; this is the planter's hay harvest; the tops serve for chaff, for dry food instead of hay, for fodder. They are cut off above the ears, collected by a cart going along the intervals or roads, and stacked for winter use. Mr. Cobbett's harvest of tops was not so successful as it might have been: this arose from his absence at the favourable opportunity for stacking.
