ing ; and chap, 5. which in bulk includes about half the volume, is on the 

 cultivation of moss. An Appendix contains testimonies in favour of the 

 utility of the new implements, which are, the Imperial Self-cleaning Plough ; 

 the Heath Self-cleaning Plough: the Kentish Skeleton Self-cleaning 

 Plough ; the improved Scotch Plough, which contains a rod from the sheath 

 of the plough to the muzzle, for being put on when the plough is wrought 

 by both horses walking in a line in the furrow. The Imperial Self-cleaning 

 Harrow is next described ; then the Self-cleaning Drill Harrow ; and lastly, 

 the new Spring Weighing Machines. All these implements have been very 

 much approved of in different parts of Scotland; but being chiefly 

 calculated for land in an imperfect state of cultivation, or where very 

 rough stubbles are left, it may be doubted if they will come into general use. 



Sweet, Mr. Robert, F.L.S. The British Warblers ; or, Account of the 

 Genus Sylvia ; in one Fasciculus ; illustrated by Six beautifully coloured 

 Figures, taken from living Specimens iu the Author's Collection ; with 

 Directions for theirTreatment according to the Author's Method; in which 

 is explained, how the interesting and fine Singing Birds belonging to this 

 Genus may be managed, and kept in as^ood health as any common Birds 

 whatever. London. 8vo. Plates. 



" The British species belonging to this interesting genus are chiefly birds 

 of passage, visiting this country in spring, and leaving it again in autumn. 

 Several of them are deservedly esteemed as the finest songsters of all the 

 feathered race : the nightingale, in particular, has the sweetest and 

 most pleasing note of any kind at present known. It has been generally 

 supposed that they are very difficult to preserve in confinement ; but the 

 author of this work has succeeded well in preserving the greater part of the 

 most interesting species through several winters in perfect health, and most 

 of them are in full song all the winter." 



" They will succeed very well in a warm room in winter, or, if convenient, 

 any part of a hot-house or warm conservatory would suit them admirably; 

 but they require a little fresh air when the weather is mild; they may be 

 preserved in cages, either separately, or several together ; or in a small 

 aviary, where all the species might be intermixed. The temperature of the 

 room where they are, ought never to be much below temperate, though 

 several of the species do not mind a slight frost ; the sorts that the author 

 has found to suffer most from cold, are S. rubetra (the Whinchat), and 

 S. phcenicurus (the Redstart) ; the Nightingale (S. luscinia) is not near so 

 tender as these ; S. cinerea, S. sylviella, and S. atricapilla, scarcely seem to 

 mind the cold at all." 



We recommend this work to our horticultural readers, because we think 

 singing birds of different species, native as well as exotic, form a great 

 addition to the flower garden, and botanic hot-houses. In the former we 

 would distribute different sorts in cages in the day time, taking them in at 

 night ; in the latter we would hang up cages also ; for the birds when left to 

 fly about, as in the hot-houses at Schoenbriinn, are apt to dirty the leaves 

 of the plants, besides requiring certain arrangements of wire-work to prevent 

 their escape.

of St. Vincent. Glasgow. 4to. 4 plates. 



This garden is stated to owe its origin to the Society of Arts, and to have 

 been commenced under Governor General Melville, 1765. It consisted at 

 first of twenty acres, but was afterwards increased to thirty-nine and a half. 

 Dr. George Young, Surgeon to the Forces, the principal medical officer 

 stationed in the island, was first intrusted with the charge of the ground, 

 which he held for many years. In 1774 the doctor made a report of his 

 progress to the Society of Arts, which they were pleased to reward with a 

 present of fifty guineas. In the troubled times which succeeded, the
