British tenants had sixty acres apiece, but they could lay out nothing without leases, and were all going away. The rest, says Pynnar, 'is let to twenty Irish gentlemen, as appeareth by the Rent-roll, which is contrary to the articles of plantation; and these Irish gentlemen have under them, as I was informed by the tenants and gentlemen in the country, about 3,000 souls of all sorts.' Thus were sown the dragon's teeth which in due time produced the rebellion of 1641.[67] [Sidenote: Londonderry and Coleraine.] The fate of Randolph's and Docwra's settlements, or perhaps the fear that O'Cahan might yet be restored, prevented applications for grants in the county of Coleraine or what is now known as Londonderry. It occurred to James or to Salisbury that the difficulty could be got over by offering the whole district to the city of London, whose wealth might enable them to settle and defend it. The suggestion was made to the Lord Mayor, who on July 1, 1609, directed each of the City companies to name four representatives for the discussion of the subject. In addition to the published papers a special document was communicated to the City in which the advantages of the settlement were duly set forth. Derry might be made impregnable, and probably Coleraine also, and charters with great privileges were offered for each. The negotiations which followed were not conducted by the Irish Government, but between the Privy Council and the City direct. On January 28, 1610, articles were agreed upon by which the Corporation bound themselves to lay out 20,000_l._ and to build within two years 200 houses at Derry and 100 at Coleraine, sites being provided for 300 more in the one case and for 200 in the other. Afterwards they were allowed to finish building at Coleraine before beginning at Derry, conditional on their making the fortifications there defensible before the winter of 1611. The whole county, with trifling exceptions, was granted to the City in socage, and they had the ecclesiastical patronage within the two new towns and the fisheries of the Foyle and the Bann. It was not intended that there should be any delay in setting to work, and the Londoners undertook to build sixty houses at Derry and forty at Coleraine before November. On the other hand the King covenanted to protect them until they were strong enough to protect themselves, and to give his consent to such legislation as might be found necessary. Formal charters were not, however, granted until 1613.[68] [Sidenote: Sir Thomas Phillips.]
