But Curwen's feverish secret activities by no means ceased with this change. On the contrary, they tended rather to increase; so that more and more of his shipping business was handled by the captains whom he now bound to him by ties of fear as potent as those of bankruptcy had been. He altogether abandoned the slave trade, alleging that its profits were constantly decreasing. Every possible moment was spent at the Pawtuxet farm; though there were rumours now and then of his presence in places which, though not actually near graveyards, were yet so situated in relation to graveyards that thoughtful people wondered just how thorough the old merchant's change of habits really was. Ezra Weeden, though his periods of espionage were necessarily brief and intermittent on account of his sea voyaging, had a vindictive persistence which the bulk of the practical townsfolk and farmers lacked; and subjected Curwen's affairs to a scrutiny such as they had never had before.
