Recently, at Edinburgh, we saw in operation an implement which combines the advantages of the hoe on an extensive scale, a harrow, a grubber, or fork, and a plough, or, rather, a machine for earthing up potatoes, etc - all this in one, and easily worked by one person. Of its great utility we cannot possibly speak too highly, and to market gardeners especially, and in those establishments where kitchen gardening is carried on extensively, it will be most valuable. The inventor of this multum in parvo instrument is C. K. Sivewright, Esq., of Edinburgh, who had it tested in the presence of a few who are interested in horticultural pursuits. Its cost is about £4 [or twenty dollars.] The implement is so constructed that it can be used with five hoes or cutters, and, by means of a simple contrivance, it can be extended or reduced to a width of from twelve inches to two feet. By removing the cutters, and inserting iron teeth about eight inches in length, in can be made to answer the purpose of a fork; and by moving these, and placing side knives in the form of a plough, ridges can be thrown up with great ease.

We were told that the saving of labor with one of these implements was very great, one man doing easily and most effectively the work of four; indeed, we are quite convinced that it is of great practical utility in the culture of turnips, cabbage, and other green crops. - London Florist.
