All I shew'd them, all I Said to them, was perfectly amazing; but above all, the Captain admir'd my Fortification, and how perfectly I had conceal'd my Retreat with a Grove of Trees, which having been now planted near twenty Years, and the Trees growing much faster than in England, was become a little Wood, and so thick, that it was unpassable in any Part of it, but at that one Side, where I had reserv'd my little winding Passage into it: I told him, this was my Castle, and my Residence; but that I had a Seat in the Country, as most Princes have, whither I could retreat upon Occasion, and I would shew him that too another Time; but at present, our Business was to consider how to recover the Ship: He agreed with me as to that; but told me, he was perfectly at a Loss what Measures to take; for that there were still six and twenty Hands on board, who having entred into a cursed Conspiracy, by which they had all forfeited their Lives to the Law, would be harden'd in it now by Desperation; and would carry it on, knowing that if they were reduc'd, they should be brought to the Gallows, as soon as they came to England, or to any of the English Colonies; and that therefore there would be no attacking them, with so small a Number as we were.

船长特别欣赏我的防御工事，欣赏我用一片小树林把住宅完全隐蔽起来。这片小树林现在已经栽了二十年了，由于这里树木比英国长得快，现在已经成了一片小小的森林，而且十分茂密。我在树林里保留了一条弯弯曲曲的小径，其他任何地方都走不进来。我告诉他，这是我的城堡和住宅，但是，像许多王公贵人一样，我在乡间还有一所别墅。如果需要，我可以去那儿休养一段时期。我说，以后有时间，我可以带他们到那儿去看看，但目前我们的首要任务是要考虑收复那只大船的问题。船长同意我的看法，可是，他说，他一时想不出什么办法，因为大船上还有二十六个人。他们既已参加了叛乱，在法律上已犯了死罪，因此已别无出路，只好一不做二不休，硬干到底。因为，他们知道，如果失败了，一回英国或任何英国殖民地，他们就会被送上绞架。但光靠我们这几个人，是无法向他们进攻的。

West of the pine barrens, the sandy soils give way to finertextured loams, and the empty forests yield to fields of alfalfa and corn, of tomatoes and asparagus.
