Almost as a natural consequence of what has now been said, in March, 1636, we find that provision was made "for having sufficient fences to the Cornfielde before the 14th of the next second month (April); that for every defective rod then found, five shillings penalty;" and it was further provided, "The field toward Rocksberry to be looked into by Jacob Elyott and Jonathan Negoose; the Fort Hill, by James Penn and Richard Gridley; the Mylne field, by John Button and Edward Bendall, and the New Field by John Audley and Thomas Faireweather." Thus it will be seen, if the rule adopted was carried out, that there were four or more large cornfields in Boston, and that the principal work of the people for a time was the raising of corn. At a later period parcels of corn were occasionally presented or sent to the governor by the Indians, who had their cornfields before the English people arrived. In fact, it is recorded in the next month after the arrival of Winthrop, that so much provision had been sold to the Indians for beaver, that food became scarce; and in October, 1630, a vessel was sent to the Narragansetts to trade, and brought home one hundred bushels of corn. In May, 1631, corn in Boston was ten shillings a bushel, as probably much was required for planting at this time. In August, 1633, a great scarcity of corn was reported; and in November, the next year, a vessel arrived from Narragansett with five hundred bushels of Indian corn. It is very clear that corn was very early, and for some time, the great dependence of the settlers. In Plymouth Colony, in 1630, the salary of the messenger of the General Court was thirty bushels of corn. In 1685, the secretary's wages was fifteen pounds a year, payable in corn at two shillings per bushel. In 1690, "one third the Governor's salary ordered to be paid in money, the rest in corne." In 1637, April 16, "all the fences and gates to be made up. Sargeant Hutchinson and Richard Gridley to look after the Fort Field; John Button, James Everett and Isaac Grosse, in the Mill Field; Wm Colburn and Jacob Elyott on the Field next Roxburie." Again, in 1640, March 30, "To look to the fences: Richard Fairbanks and William Salter the field towards Roxbury; Benj. Gillam and Edmd. Jacklyn, the Fort Field; Wm. Hudson and Edward Bendall the New Field; Mr. Valentine Hill and John Button, the Mill Field."
