So,— I would reapectfully call your attention to a groM fraud wiwht to h» pwpetrated upMi the farmer* of Canada by tiM tale of an artide offered at Kato^s Plant Food; tbe manufacturers having their Canadian Acenojr at ObatbAm, Ont The article in queation ia merely a cradied rock of the Syenite tgm loch a* ^xirta in UmitloM quantity at y&ty many plaoaa in Canada, where it ia naed for macadamising rosds, and other purpoaea.
