At the close of the Revolution the States of South Carolina and Georgia presented large tracts of land to the gallant General Nathaniel Greene, to whose genius they were indebted for their relief from British tyranny. Soon after this grant was made, General Greene removed his family to Mulberry Grove, a fine plantation on the Georgia side of the Savannah River. Here he died in 1786, from sunstroke, but his family continued to reside on the place. The mansion of Mrs. Greene was noted for its hospitality, and was frequently filled with guests who came to pay their respects to the widow of the most brilliant and best trusted subordinate of the immortal Washington. To this mansion there came one day, in the year 1792, ELI WHITNEY, then a young man recently from New England. He was a native of Westborough, Massachusetts, where he was born on the 8th of December, 1765. Of his youth but little is known, save that he was gifted with unusual mechanical genius, the employment of which enabled him to overcome some of the difficulties incident to his poverty, and to acquire the means of obtaining a good common school education. Adding to this the labors of a teacher, he earned a sum sufficient to carry him through Yale College, where he was graduated in the summer of 1702, a few months before his arrival in Georgia. He had come South to accept the offer of a situation as teacher, but the place had been filled before his arrival, and, being without friends in that section, he sought employment from Mrs. Greene. Though pleased with his modesty and intelligence, that lady could not avail herself of his services as a tutor, but invited him to make her house his home as long as he should desire to remain in Georgia. He was sick in body and disheartened by his first failure, and gladly accepted her invitation. While her guest he made her a tambour frame of an improved pattern, and a number of ingenious toys for her children, which so delighted the good lady that she enthusiastically declared him capable of doing any thing. Not long after Mr. Whitney's arrival at the plantation, Mrs. Greene was entertaining a number of visitors from the surrounding country, several planters of considerable wealth being among the number, when one of the guests turned the conversation upon the subject of cotton-raising, by declaring that he had met with such poor success that he was ready to abandon the undertaking. His trouble was not, he said, that cotton would not grow in his land, for it yielded an abundant return, but that the labor of clearing it from the seed was so enormous that he could not do more than pay expenses after selling it.
