The amount of labor which he is capable of undergoing is astonishing. While engaged in carrying out his inventions, it is a common thing for him to pass sixteen hours a day at his table, in the execution of detailed mechanical drawings, which he throws off with a facility and in a style that have probably never been surpassed. He does not seem to need such recreation as other men pine after. He never cares to run down to the seashore, or take a drive into the country, or spend a week at Saratoga or at Newport. Give him his drawing-table, his plans, his models, the noise of machinery, the clatter of the foundry, and he is always contented. Week in and week out, summer and winter, he works on and on,--and the harder he works, the more satisfied he seems to be. He is as untiring as one of his own engines, which never stop so long as the fire burns. Endowed with such a constitution, it is to be hoped that new triumphs and many years of honor and usefulness are yet before him. * * * * * MOVING. Man is like an onion. He exists in concentric layers. He is born a bulb and grows by external accretions. The number and character of his involutions certify to his culture and courtesy. Those of the boor are few and coarse. Those of the gentleman are numerous and fine. But strip off the scales from all and you come to the same germ. The core of humanity is barbarism. Every man is a latent savage. You may be startled and shocked, but I am stating fact, not theory. I announce not an invention, but a discovery. You look around you, and because you do not see tomahawks and tattooing you doubt my assertion. But your observation is superficial. You have not penetrated into the secret place where souls abide. You are staring only at the outside layer of your neighbors; just peel them and see what you will find. I speak from the highest possible authority,--my own. Representing the gentler half of humanity, of respectable birth, tolerable parts, and good education, as tender-hearted as most women, not unfamiliar with the best society, mingling, to some extent, with those who understand and practise the minor moralities, you would at once infer from my circumstances that I was a very fair specimen of the better class of Americans,--and so I am. For one that stands higher than I in the moral, social, and intellectual scale, you will undoubtedly find ten that stand lower. Yet through all these layers gleam the fiery eyes of my savage. I thought I was a Christian, I have endeavored to do my duty to my day and generation; but of a sudden Christianity and civilization leave me in the lurch, and the "old Adam" within me turns out to be just such a fierce Saxon pirate as hurtled down against the white shores of Britain fifteen hundred years ago. For we have been moving.
