 trim our sails between chemistry and history. I like the historical method best. If I say that William the Conqueror came over in 1492, and Columbus discovered America in 1100 or 1066 or whenever it was, that's a mere detail that the Professor overlooks. It gives a feeling of security and restfulness to the history recitation, that is entirely lacking in chemistry.

Sixth-hour bell—I must go to the laboratory and look into a little matter of acids and salts and alkalis. I've burned a hole as big as a plate in the front of my chemistry apron, with hydrochloric acid. If the theory worked, I ought to be able to neutralize that hole with good strong ammonia, oughtn't I?

Examinations next week, but who's afraid?

Yours ever,
