One of the most extraordinary of these incidents beyond question is this, which I will here record, not only because it concerns Lambert, but because it perhaps was the turning-point of his scientific career. By the law of custom in all schools, Thursday and Sunday were holidays; but the services, which we were made to attend very regularly, so completely filled up Sunday, that we considered Thursday our only real day of freedom. After once attending Mass, we had a long day before us to spend in walks in the country round the town of Vendome. The manor of Rochambeau was the most interesting object of our excursions, perhaps by reason of its distance; the smaller boys were very seldom taken on so fatiguing an expedition. However, once or twice a year the class-masters would hold out Rochambeau as a reward for diligence. In 1812, towards the end of the spring, we were to go there for the first time. Our anxiety to see this famous chateau of Rochambeau, where the owner sometimes treated the boys to milk, made us all very good, and nothing hindered the outing. Neither Lambert nor I had ever seen the pretty valley of the Loire where the house stood. So his imagination and mine were much excited by the prospect of this excursion, which filled the school with traditional glee. We talked of it all the evening, planning to spend in fruit or milk such money as we had saved, against all the habits of school-life. After dinner next day, we set out at half-past twelve, each provided with a square hunch of bread, given to us for our afternoon snack. And off we went, as gay as swallows, marching in a body on the famous chateau with an eagerness which would at first allow of no fatigue. When we reached the hill, whence we looked down on the house standing half-way down the slope, on the devious valley through which the river winds and sparkles between meadows in graceful curves--a beautiful landscape, one of those scenes to which the keen emotions of early youth or of love lend such a charm, that it is wise never to see them again in later years--Louis Lambert said to me, "Why, I saw this last night in a dream."
