In the evening I preached by engagement for the Rev.— —, in the — Presbyterian Church. It was pouring with rain, and not more than 150 persons were present. The pastor, who had visited me in a very fraternal manner, kindly proposed to devote part of the next day to showing me some of the “lions” of the city. The first place we visited was Mount Vernon, the institution of the Abbotts. It is a seminary for young ladies, with 200 pupils. The first of the brothers to whom we were introduced was John Abbott, the author of “The Mother at Home.” He is apparently 40 years of age. He introduced us to the room of the senior class, which consisted of 30 or 40 young ladies, from 14 to 25 years of age. They were engaged in a French exercise with Jacob Abbott, the author of “The Young Christian,” “The Corner Stone,” “The Way for a Child,” &c, &c. The exercise over, we were introduced to Mr. Jacob Abbott, and were requested to accompany him to a private sittingrroom. I found him an exceedingly pleasant and unassuming man. He is 43 years of age, but looks younger. He wrote both “The Young Christian” and “The Corner Stone” when he was only 25. John is two years younger than Jacob; Charles, to whom also I was introduced, is younger still; and Gorham, whom I did not then see, is the youngest of the four.
