EMPLOYMENT.—Persons having a little time to spare, are apprised that Agents continue to be appointed in London and Country Towns by the EAST INDIA TEA COMPANY, for the sale of their celebrated TEAS (Offices, 9, Great St Helen's Churchyard, Bishopsgate-street). They are packed in showy leaden canisters, from an ounce to a pound, with the prices and weight marked on each packet, and but little trouble is occasioned by the sale; the license is only 11s. per annum, and many, during the last nineteen years, have realised considerable incomes by the Agency, without 1s. let or loss. Application to be made (if by letter, post paid) as above.
