It is curious why anybody should pooh-pooh a study of fossils or various forms of rocks or lava. Such things grant us our only vision into Natural History's big book; and it isn't a book in first-class condition. Far from it! Just a tiny scrap; a slip; or, possibly a big chunk is found, with nothing notifying us as to how it _got_ to that particular point, nor how long ago. Man can only look at it, lift it, rap it, cut into it, and squint at it through a magnifying glass. And,--_think_ about it. That's all; until a formal study brings accompanying thoughts from many minds; and, by such tactics, judging that in all probability such and such a rock or fossil footprint is about so old. Natural History holds you in its grasp through just this impossibility of finding actual facts; for it is thus causing you to _think_. Now, thinking is not only a voluntary function; it is an _acquisition_; an _art_. Plants do not think. Animals probably do, but in a primary way, such as an aid in knowing poisonous foods, and how to bring up an offspring with similar ability. But Man can, and _should_ think, and think hard and constantly. It is ridiculous to rush blindly into an action without looking forward to lay out a plan. Such an unthinking custom is almost a panic, and panic is but a mild form of insanity. So Kathlyn and Julius did a grand, good thing in having this Hall as an addition to Branton Hills' institutions. Now, in any city or town, or almost any small community, you will find a building, or possibly only a room, about which said city or town has nothing to say. It is that most important institution in which you put a stamp on your mail and drop it into a slot, knowing that it will find its way across city or country to that man or woman who is waiting for it. But how many young folks know _how_ this mail is put out so quickly, and with such guaranty against loss? Not many, I think, if you ask. So Gadsby, holding up Youth as a Nation's most important function in its coming history, thought that any act which would instruct a child in any way, was worthy. So, on a Saturday morning His Honor took a group of Grammar School pupils to a balcony in back of that all-hiding partition, and a postal official, showing all mail handling acts individually, said:--
