taken up and collected into heaps, as soon as they have acquii-ed maturity, 

 they will germinate in autumn, and be fit for use, without being boiled, through 

 the winter. Potatoes of such varieties, are, however, wholly unfit for human 

 food, late in the spring; and for such purpose those of later and less excitable 

 habits must be cultivated. Of such kinds, in the last season, which was not 

 favourable, owing to the plants having suffered injury from drought, I obtained 

 a produce varying from 20 to 24 tons per acre, the soil being naturally light 

 and poor, and not more highly manured than would have been necessary for 

 a crop of Swedish turnips."

THEKyanisingofWoodfor Garden Purposes. — When we mention that Messrs. 

 Loddiges have used no other wood, for several months past, in constructing 

 sashes, rafters, in making tallies for naming plants, and even rods for tying them 

 to, we think we have said enough to show the practical value of the process of 

 Kj'anising. We trust, therefore, that every gardener who sees this will direct 

 his master's attention to the subject, as likely to produce a considerable saving 

 in the annual expense of keeping up gardens and hot-houses. Even the saving 

 of labour in cutting tallies and rods for tying plants to, where there are exten- 

 sive collections, is not unworthy of notice ; independently altogether of the 

 greatly increased durability of the wood employed for rafters, hot-bed frames, 

 sashes, trellis-work, doors, fences, wheelbarrows, seats, sheds, summer-houses, 

 plant-boxes, &c. It has been stated to us, on an authority on which we think 

 we can rely, that, where articles are cut into the forms required, such as tallies, 

 props for rods, &c., brushing them over with a solution of corrosive sublimate 

 will be found sufficient to insure durability ; but, as the price of Kyanising is 

 a mere trifle, we scarcely think it worth while for any one to attempt it him- 

 self. The Hon. and Rev. W. Herbert has tried a solution of alum water, and 

 found it effective in preserving birds ; and he has suggested to us that it might 

 be tried for preserving wood, such as tallies, rods, &c. We believe Mr. Her- 

 bert is making some experiments in this way himself, and we would suggest a 

 trial to gardeners and naturalists, since it involves very little expense. — Cond. 



" A Botanical Collector to discover the chief Beauties of any particular District, 

 should visit all its principal hills and valleys, woods and plains, not less than six 

 times in the year. To do so in the least degree satisfactorily, and prepare a 

 partial herbarium of the district, a space of country 30 miles square would, on 

 the average, including barren parts and water, prove an ample portion, even for 

 a cursory examination. Now, as America alone contains about 15,000,000 of
