The Managing Committee of this excellent Institution have resolved to make an effort to raise the pensioners' allowances from £16 and £12 to £20 and £16 per annum to male and female pensioners respectively. To enable the Committee to attain this desirable end, they purpose carrying out a scheme proposed by the secretary, Mr Cutler, of appealing to the gardeners of Great Britain, and recommending that a simultaneous collection be made in every garden in the kingdom on Saturday the 30th of July next. To alleviate the privations of aged and indigent gardeners and their widows, who have either from old age or misfortune been reduced to poverty, is surely a laudable object, and we wish the proposed scheme every success.
