Dr. Anderson is of opinion, that a few hours sun-shine will at any time be sufficient completely to heat the house in which vines are planted; and thus, without any artificial heat from fuel, a perma- nent warmth may be maintained, which is sufficient to ripen gripes, in favourable weather, as early as in the months of June, July, and August. He farther suggests diat the upper chamber may be convert- ed into an hot-house ot inferior rank j and that it would be emi- nently calculated to serve as a sub- stitute for a green-house or conser- vatory. Such is the outline of this very ingenious plan, and the inquisitive reader who wishes to acquire more minute information on this subject, will probably resort to the volume already quoted, where it is amply treated, and illustrated with cuts. Hot-houses are liable to be in- fested with a variety of insects known under the different appella- tions of Cocci, Aphides (lice), &c. that harbour in the walls, and among the trellises, which fasten up vines, and other wall-fruit trees, especially during the winter. In order to destroy these vermin, Mr. Speechley recommends the walls to be washed with common soap- suds, early in the spring, while they arc in a torpid state: this li- quor is to be poured out of a wa- tering-pot from the top of the wall downwards ; and ought, wlu nus< d, to be considerably wanner than new milk: thus, if the su properly and plentifully apj the wall will assume a pale red co- lour, and the insefits be effectually destroyed. HOUXD, an appellation given to dogs oi~ chace. Hounds of the middle kind are deemed to be the best, being stronger than* such as are either very small, or of a large size.— The shape of these animals should be carefully attended to, as they can neither rim swift, nor perform great tasfcs, if their limbs are not well proportioned. A good hound ought to have straight legs, round small feet, and well-formed shoul- der's] his breast should be rathef wicle than narrow • his chest deep; his back broad ; his head small ; his neck thin ; his tail thick and bushy. Young animals that are weak from the knee to the foot, should not be suffered in the pack ; and all the hounds shoukl be nearly of a size. Particular attention is requisite in the breeding of hounds. No old dogs should be admitted, nor should any attempts be made to cross the breed. The months of January, February, and March, are the best for breeding. — As, however, this- quadruped is less connected with purposes of economy than amuse- ment, we shall content ourselves with referring the curious reader to Mr. Beckford's " Thoughts on Hunting," (4to. 10s. 6d.) in which the subject is fully and perspicuous- ly treated. , Hound's-berry.
