The advice of a scholar, whose piles of learning were set on fire by imagination, is never to be forgotten. Proportion an hour's reflection to an hour's reading, and so dispirit the book into the student.

Association is the delight of the heart, not less than of poetry. Alison observes that an autumn sunset, with its crimson clouds, glimmering trunks of trees, and wavering tints upon the grass, seems scarcely capable of embellishment. But if in this calm and beautiful glow the chime of a distant bell steal over the fields, the bosom heaves with the sensation that Dante so tenderly describes.

A book becomes a mirror, with the author's face shining over it. Talent only gives an imperfect image,--the broken glimmer of a countenance. But the features of genius remain unruffled. Time guards the shadow. Beauty, the spiritual, Venus,--whose children are the Tassos, the Spensers, the Bacons,--breathes, the magic of her love, and fixes the face forever.

The history of men of science has one peculiar advantage, as it shows the importance of little things in producing great results. Smeaton learned his principle of constructing a lighthouse, by noticing the trunk of a tree to be diminished from a curve to a cyclinder ... and Newton, turning an old box into a water-clock, or the yard of a house into a sundial, are examples of those habits of patient observation which scientific biography attractively recommends.

Attention makes the genius; all learning, fancy, science and skills depend upon it. Newton traced his discoveries to it. It builds bridges, opens new worlds, heals diseases, carries on the business of the world. Without it taste is useless, and the beauties of literature unobserved.

It is supposable that, in the eyes of angels, a struggle down a dark lane and a battle of Leipsic differ in nothing but excess of wickedness.

Genius is nourished from within and without.
