The children were not altogether happy there, as Alexander wrote a friend years afterward. "Vine-clad hills which here we call mountains, extensive plantations of foreign trees, the meadows surrounding the house, and lovely views of the lake with its picturesque banks awaiting the beholder at every turn, render this place undoubtedly one of the most attractive residences in the neighborhood. If, in addition, you picture to yourself the high degree of luxury and taste that reigns in our home, you will indeed be surprised when I tell you that I never visit this place without a certain feeling of melancholy.... I passed most of that unhappy time (my youthful days) here at Tegel, among people who loved me, and showed me kindness, but with whom I had not the least sympathy, where I was subjected to a thousand restraints and much self-imposed solitude, and where I was often placed in circumstances that obliged me to maintain a close reserve, and to make continual self-sacrifices. "Now that I am my own master, and living here without restraint, I am unable to yield myself to the charms of which nature is here so prodigal, because I am met at every turn by painful recollections of my childhood, which even the inanimate objects around me are continually awakening. Sad as such recollections are, however, they are interesting from the thought that it was just my residence here which exercised so powerful an influence in the formation of my character and the direction of my tastes to the study of nature." Much which seems trying and unsatisfactory is, after all, our best discipline for life. The strongest and noblest characters are not developed in the perpetual sunshine of happiness. Rain and sun are alike necessary for growth.
