Cryptogram from Frankenstein; or, the modern prometheus, chapter 2

The sentence you are solving goes here.

On the birth of a second son, my junior by seven years, my parents gave up entirely their wandering life and fixed themselves in their native country. We possessed a house in Geneva, and a campagne on Belrive, the eastern shore of the lake, at the distance of rather more than a league from the city. We resided principally in the latter, and the lives of my parents were passed in considerable seclusion. It was my temper to avoid a crowd and to attach myself fervently to a few. I was indifferent, therefore, to my school-fellows in general; but I united myself in the bonds of the closest friendship to one among them. Henry Clerval was the son of a merchant of Geneva. He was a boy of singular talent and fancy. He loved enterprise, hardship, and even danger for its own sake. He was deeply read in books of chivalry and romance. He composed heroic songs and began to write many a tale of enchantment and knightly adventure. He tried to make us act plays and to enter into masquerades, in which the characters were drawn from the heroes of Roncesvalles, of the Round Table of King Arthur, and the chivalrous train who shed their blood to redeem the holy sepulchre from the hands of the infidels.
