Charlock, WildMustard, Chadlock, or Corn-Cale, the Sinapis arvensis, L. an indigenous plant, which grows in corn and turnip fields. It is a very noxious weed, especially among turnips, to which it bears so great a resemblance, that it is said, instances have occurred, of hoers taking up a whole crop of turnips, and leaving the charlock. To obviate this evil, it has been recommended to turn a flock of sheep into a field abound-with this weed; for, during the early period of its growth, they will prefer it to the crop. Some lands are exceedingly liable to be overrun with the charlock, particularly when they have been manured with cow-dung alone, as that is very favourable to its growth. Experienced farmers, in general, are so well convinced of this effect, that they always mix horse-dung with that of cows, for manuring arable land. When barley is infested with charlock, to such a degree as to en-danger the crop, that weed has down with success in the month of May, while in flower ; but care should be taken to cut off, the same time, the tops of the barley leaves. Thus, the latter will shoot up above the weed ; and it is a remarkable la6r, that four quarters of grain have been obtained from such land as, without this expedient, would have been almost unproductive.

The most effectual method of extirpating the charlock is, to sow arable land with grass-seeds, and thus convert it into pasture; because the former never grows where a coat of grass covers the ground.

When this plant annives at maturity, it produces yellow flowers, and turgid, angular pods, contain 1115 seed, which is commonly sold under the name of Durham mustand

In Ireland, and the northern parts of Europe, this plant is boiled, and eaten in the same manner as cabbage. It is also relished by cows, goats, and swine ; sheepaie extremely fondof it ; bat it is gene-rally refosed by horses. Bee de-rive much nourishment from its

Instead of being spurisously vend-ed for Darham mustard, the seeds of this plant might be rendered more profitable, by expressing the excellent od wish which they abound. This has been attempted with success, in Germany; for we are informed by Bechsteiik, that he obtained thirty pounds of pare lamp-oil, from one hundred pounds esessCharr, the Ran, or Case-CKitt, Salmo alphas, or itaulc auinor, a species of fish bat seldom found in British lakes, though abundantly in the colder ones of the Lapiand Alps. It delights in clear and pure waters, and rarely wanders into running streams.

According to Mr. PENNANT, the largest and most beautiful of these Fish . are caught in the lake of Win-denmere, Wesumoreland. It spawns about Michaelmas, and chiefly in the river Brathery, which forms a confluence with another, called the Rowthay, When both disgorge themselves into the lake. The former has a bleck rocky bottom ; of the latter, a bright sand, which is never visited by the charr. These fish are said to be in the highest perfection about May, and to continue so the whole summer, yet are seldom caught alter In the spawning season, they will take bait, but at no other time, and are commonly caught in breast-nets, about twenty-four fathoms long, and five breed.—They are likewise taken, though in smaller • quantities, in lakes or pools at the foot of Mount Snowden, in Wales, where this fish is called torgoch, and esteemed a greater dehcacy than the trout.

The flesh of the charr is very red, and, when potted, delicious eating; hence, numbers of them are annually seat to London.
