Destruction of Caterpillars. — An order of the State Deputies of our pro- 

 vince ordains, under the penalties estabhshed by law, the destruction of the 

 caterpillars on the trees and hedges, at two different periods of the year; 

 viz, the 25th of March, and on or before the 2.5th of the April following. 

 {Jour, de la Belgicjue.) 



Leaves of the Mulberry. — The mulberry tree is found in different cli- 

 mates, but the juice of leaves grown in the north is much less nutritive 

 than that of the leaves of the south. In this respect mulberry leaves and 

 silk are not less different than wines, according to the climate in which 

 they are produced. In general, every climate and soil that will produce 

 good wheat will produce large succulent mulberry leaves ; but these leaves 

 will be too nutritive ; they will have too much sap, too much substance 

 and succulency. The wild mulberry, with small leaves, answers better for 

 such a soil, than the grafted mulberry with large leaves. A general rule, 

 and one to be depended on, is, that the mulberry to produce the best silk 

 requires the same soil and exposure that the vine does to produce the best 

 wine. Experience has proved that silk worms nourished by leaves gathered 

 from a dry soil, succeed much better, produce more cocoons, and are less 

 subject to those diseases which destroy them, than those which have been 

 nourished by leaves produced by an extremely rich soil. {Un Pepinieriste 

 de la Belgique, in the Journal d'Agric. des Pays-Bas, Oct. 1827, p. 217.) 



Nurseries. — In the Journal d' Agricidliire des Pays-Bas for October, it is 

 stated by the editor, that those which may be best depended upon for fruit 

 trees are, the nursery of Perck near Vilvorde, and the nursery of Freloux 

 near Liege. 



The Manufacture of Sugar from the Beet Root is said to be on the in- 

 crease, and, though the sugar of the Colonies is always somewhat cheaper 

 in the Netherlands than in France, is said to pay the manufacturer. It is 

 stated, however, that a profit is more certain where the manufacturer is 

 also the grower. A part of the advantage arises from giving the leaves and 

 the refuse of the manufacture of the root to cattle, and from the quantity 

 of manure produced. {Jour, d' Agriculture des Pays-Bas, Oct. 1827. p. 231.) 



Le Poudre Saline. — A patent is taken out for a manure so named, by 

 M. Depup of Brussels ; it is said to answer particularly well for clover. {lb.)

Opium has been recently cultivated to a considerable extent in England, 

 particularly by a Mr. Young, and Messrs. Cowley and Staines of Winslow j 

 and, among physicians and surgeons, the English opium is considered to be 

 superior to the best Turkey and East India opium. {Mech. Mas,., Feb. 2. 

 1828.) 



Zoological Society. — The Commissioners of Woods and Forests have 

 granted to the Zoological Society the whole of the lake in the Regent's 

 Park, with the islands, the waterfowl, and a convenient site in the neigh- 

 bourhood of the lake, for erecting premises for breeding, rearing, and trying 

 experiments. Some valuable privileges have been annexed to this judicious 

 gift, which is of essential consequence in itself; but peculiarly gratifying, as 

 testifying the favour of Government, and the interest which "it takes in the 

 progress of useful science. {Mech. Mag., Feb. 9. 1828.) We have already 

 (Vol. III. p. 469.) expressed our wish that the botanic garden of the London 

 University might be joined to the zoological garden ; and we think, if 

 the whole of the space in the central circle, about ten acres, were granted
