Do a little more of that work which you have sometime confessed to be good, which you feel that society and your justest judge rightly demands of you. Do what you reprove yourself for not doing. Know that you are neither satisfied nor dissatisfied with yourself without reason. Let me say to you and to myself in one breath, Cultivate the tree which you have found to bear fruit in your soil. Regard not your past failures nor successes. All the past is equally a failure and a success; it is a success in as much as it offers you the present opportunity. Have you not a pretty good thinking faculty, worth more than the rarest gold watch? Can you not pass a judgment on something? Does not the stream still rise to its fountain-head in you? Go to the devil and come back again. Dispose of evil. Get punished once for all. Die, if you can. Depart. Exchange your salvation for a glass of water. If you know of any risk to run, run it. If you don’t know of any, enjoy confidence. Do not trouble yourself to be religious; you will never get a thank-you for it. If you can drive a nail and have any nails to drive, drive them. If you have any experiments you would like to try, try them; now’s your chance. Do not entertain doubts, if they are not agreeable to you. Send them to the tavern. Do not eat unless you are hungry; there’s no need of it. Do not read the newspapers. Improve every opportunity to be melancholy. Be as melancholy as you can be, and note the result. Rejoice with fate. As for health, consider yourself well, and mind your business. Who knows but you are dead already? Do not stop to be scared yet; there are more terrible things to come, and ever to come. Men die of fright and live of confidence. Be not simply obedient like the vegetables; set up your own Ebenezer. Of man’s “_dis_obedience and the fruit,” etc. Do not engage to find things as you think they are. Do what nobody can do for you. Omit to do everything else.[34] * * * * * According to Lieutenant Davis, the forms, extent, and distribution of sand-bars and banks are principally determined by tides, not by winds and waves.[35] On sand-bars recently elevated above the level of the ocean, fresh water is obtained by digging a foot or two. It is very common for wells near the shore to rise and fall with the tide. It is an interesting fact that the low sand-bars in the midst of the ocean, even those which are laid bare only at low tide, are reservoirs of fresh water at which the thirsty mariner can supply himself. Perchance, like huge sponges, they hold the rain and dew which falls on them, and which, by capillary attraction, is prevented from mingling with the surrounding brine.[36]
