62 APPENDIX. are employed in manufactures, or in making up manu- factured articles, as shoes and clothes, &c. with which the market is already supplied, they must interfere with the industry of other workmen, who would soon be reduced to poverty, and that, consequently, mischief rather than good would arise from such a system. Whereas, while there are such extensive tracts of waste land all over the kingdom, and more especially in the neighbourhood of the Metropolis, and while we are under the necessity of importing food from other countries, our agriculture cannot be too much extended. " Besides mere digging, a variety of operations might be executed by manual labour, as collecting manure, transporting it in barges up the river, conveying it to the field on portable iron railways, transplanting the crops, hoeing and weeding them, cutting down or reap- ing them, threshing by hand mills, and grinding the wheat by the flour mills, so strongly recommended by the Society of Arts. In short, the employment which agriculture furnishes, are numerous and unceasing." Captain Brenton's opinion may be seen in an answer to Mr. Wilmot Horton's Treaties in favour of emigra- tion, and in other Tracts, and in which he shows the absolute necessity of finding employment for many thousands of idle dangerous men, and of destitute boys in the Metropolis, of which he supposes that there are fifteen thousand, who have no home, but are brought up and practised in the commission of every species of vice and inquity.
