All this Labour I was at the Expence of, purely from my Apprehensions on the Account of the Print of a Man's Foot which I had seen; for as yet I never saw any human Creature come near the Island, and I had now liv'd two Years under these Uneasinesses, which indeed made my Life much less comfortable than it was before; as may well be imagin'd by any who know what it is to live in the constant Snare of the Fear of Man; and this I must observe with Grief too, that the Discomposure of my Mind had too great Impressions also upon the religious Part of my Thoughts, for the Dread and Terror of falling into the Hands of Savages and Canibals, lay so upon my Spirits, that I seldom found my self in a due Temper for Application to my Maker, at least not with the sedate Calmness and Resignation of Soul which I was wont to do; I rather pray'd to God as under great Affliction and Pressure of Mind, surrounded with Danger, and in Expectation every Night of being murther'd and devour'd before Morning; and I must testify from my Experience, that a Temper of Peace, Thankfulness, Love and Affection, is much more the proper Frame for Prayer than that of Terror and Discomposure; and that under the Dread of Mischief impending, a Man is no more fit for a comforting Performance of the Duty of praying to God, than he is for Repentance on a sick Bed: For these Discomposures affect the Mind as the others do the Body; and the Discomposure of the Mind must necessarily be as great a Disability as that of the Body, and much greater, Praying to God being properly an Act Of the Mind, not of the Body.

现在，再接着说说我接下去做的事。我把一部分家畜安置妥当后，便走遍全岛，想再找一片这样深幽的地方，建立一个同样的小圈地养羊。我一直往岛的西部走，到了一个我从前从未涉足的地方。我往海里一看，仿佛看到极远处有一只船。我曾从破船上一个水手的箱子里找到了一两只望远镜，可惜没有带在身边。那船影太远，我也说不准到底是否是船。

They tell us of the Israelites in Egypt, the Helots in Sparta, and of the Roman Slaves, which last were made up from almost every nation under heaven, whose sufferings under those ancient and heathen nations, were, in comparison with ours, under this enlightened and Christian nation, no more than a cypher--or, in other words, those heathen nations of antiquity, had but little more among them than the name and form of slavery; while wretchedness and endless miseries were reserved, apparently in a phial, to be poured out upon our fathers, ourselves and our children, by Christian Americans....

他们在那些远古和野蛮的国度堥到的磨难，与我们在这开明的基督教国家所受到的相比，的确是微乎其微了──换句话说，那些远古的野蛮国家不过具有奴隶制的名称和形式而已；而虔信基督的美国人，却将不幸和无边的苦难加以浓缩而保存了下来，灌注到我们的先辈、我们自己和我们的后代身上去。。。。。。

The interval sowing experiments showed that 291S was a photo-thermo-sensitive male sterile line, which showed part fertile under short-day and low-temperature conditions when autumn sowing, showed high sterile under long-day and high-temperature conditions when spring sowing. The self-multiplication ability and sterility of 291S can be improved through selection effectively. The pistillody of stamens of 291S could be induced under certain photoperiod and temperature condition.
