The arrival of her father with the guest he was to bring proved she had divined right. For coming up the avenue, she saw that it was the same handsome young man she had a little before encountered. And she could perceive in her father's countenance a glowing look of satisfaction as the two mounted the steps (Sarah was peeping through the blinds) and proceeded to enter the house. Before they had accomplished this, however, the room was vacant. Sarah was nowhere to be found--that is, for the moment; but in due time she presented herself, and thereupon Dr. James Egerton--that was his name--was formally introduced to her. 'I recollect you now,' said Sarah, seriously. 'Your features have not at all changed, except they seem larger and--' 'Older, doubtless,' interrupted the young man. 'You, too, have changed, even more than I; but I knew you the moment my eyes fell on you.' * * * Seven years had passed since grievous afflictions befell Joel Burns--when his wife died and his daughter was stricken low, and he himself was brought to the very gates of death. The reader has already been made acquainted with these circumstances, and will scarcely forget that, when the famous medical man returned to New Haven after visiting Sarah, he despatched his favorite student, with directions to devote himself to the case. It is known, too, with what earnestness and skill the youth--for he was little more than a youth--performed his responsible duties. Here I had thought to take leave of him, but as he has abruptly come on the stage as a visitor at Burnsville, and as Sarah Burns already exhibits an incipient interest in the young doctor, I must let the reader into the secret of his sudden appearance. THE UNION. VII. RHODE ISLAND AND DELAWARE COMPARED. In 1790 the population of Rhode Island was 69,110, and that of Delaware 59,096. In 1860 the former numbered 174,620, the latter 112,216. Thus, from 1790 to 1860, the ratio of increase of population of Rhode Island was 152.67 per cent., and of Delaware, 89.88. At the same relative rate of increase, for the next, as for the last seventy years, the population of Rhode Island in 1930, would be 441,212, and of Delaware, 213,074. Thus in 1790, Rhode Island numbered but 10,014 more than Delaware, 62,404 more in 1860, and, at the same ratio of increase, 228,138 more in 1930. Such has been and would be the effect of slavery in retarding the increase of Delaware, as compared with Rhode Island. (Census Table, 1860, No. 1.) The population of Rhode Island per square mile in 1790, was 52.15, and in 1860, 133.71; that of Delaware, 27.87 in 1790, and 59.93 in 1860. The absolute increase of population of Rhode Island, per square mile, from 1790 to 1860, was 80.79, and from 1850 to 1860, 20.74; that of Delaware, from 1790 to 1860 was 25.05, and from 1850 to 1860, 9.76.
