The prime cause of this insurrection was the granting of the land in great areas at the beginning of the century to favored proprietors, so that the actual settlers could not become owners but only tenants. Fragments of such great estates remain in the hands of certain families till our time. The ownership of Hammersley Lake by the family of that name is an example. The exercise of authority by these monopolists of natural opportunities drove the actual tillers of the soil, who had given it its value, to desperation. I have shown that in 1740 no land owners were enrolled on Quaker Hill, and that the list of its most representative citizens in 1755 contained few landowners.[20] A further cause of this conflict may have been that, in the year of the settlement of the boundaries of the Oblong it was granted to one company by the British Crown, and to another by the Colony of New York. This brought the title of all the lands on the Oblong into dispute. Moreover, boundaries were carelessly indicated and loosely described, a pile of stones or a conspicuous tree serving for a landmark. All this worked great confusion, for the settlement of which in a crude community courts were ineffective. Finally the popular discontent broke out to the north in armed refusal of settlers to pay the rents exacted. The movement spread from Dutchess to Columbia County. William Prendergast, who is said to have lived in a house standing on the ground now part of the golf links in Pawling, was the leader of the insurgents in this county. He assembled a band on Quaker Hill so formidable that the grenadiers at Poughkeepsie waited for reinforcements of two hundred troopers and two field pieces from New York before proceeding against him. The sight of the red coats was enough. Prendergast surrendered. But so great was the local excitement that, to forestall an attempt to rescue, he was taken a prisoner to New York. In July he was brought back for trial; and on the same boat with the King's counsel, judges, lawyers and prisoner came a company of soldiers to put down the continued disturbance in Columbia County.[21]
