These chapters are for children, and I shall try to make the words large enough to command respect. In the hope that you are listening, and that you have confidence in me, I will proceed. Dates are difficult things to acquire; and after they are acquired it is difficult to keep them in the head. But they are very valuable. They are like the cattle-pens of a ranch—they shut in the several brands of historical cattle, each within its own fence, and keep them from getting mixed together. Dates are hard to remember because they consist of figures; figures are monotonously unstriking in appearance, and they don't take hold, they form no pictures, and so they give the eye no chance to help. Pictures are the thing. Pictures can make dates stick. They can make nearly anything stick—particularly if you make the pictures yourself. Indeed, that is the great point—make the pictures yourself. I know about this from experience. Thirty years ago I was delivering a memorized lecture every night, and every night I had to help myself with a page of notes to keep from getting myself mixed. The notes consisted of beginnings of sentences, and were eleven in number, and they ran something like this:

“In that region the weather—” “at that time it was a custom—” “but in California one never heard—”

Eleven of them. They initialed the brief divisions of the lecture and protected me against skipping. But they all looked about alike on the page; they formed no picture; I had them by heart, but I could never with certainty remember the order of their succession; therefore I always had to keep those notes by me and look at them every little while. Once I mislaid them; you will not be able to imagine the terrors of that evening. I now saw that I must invent some other protection. So I got ten of the initial letters by heart in their proper order—I, A, B, and so on—and I went on the platform the next night with these marked in ink on my ten finger-nails. But it didn't answer. I kept track of the fingers for a while; then I lost it, and after that I was never quite sure which finger I had used last. I couldn't lick off a letter after using it, for while they could have made success certain it would also have provoked too much curiosity. There was curiosity enough without that. To the audience I seemed more interested in my fingernails than I was in my subject; one or two persons asked me afterward what was the matter with my hands.

It was now that the idea of pictures occurred to me; then my troubles passed away. In two minutes I made six pictures with a pen, and they did the work of the eleven catch-sentences, and did it perfectly. I threw the pictures away as soon as they were made, for I was sure I could shut my eyes and see them any time. That was a quarter of a century ago; the lecture vanished out of my head more than twenty years ago, but I could rewrite it from the pictures—for they remain. Here are three of them:

The first one is a haystack—below it a rattlesnake—and it told me where to begin to talk ranch-life in Carson Valley. The second one told me where to begin to talk about a strange and violent wind that used to burst upon Carson City from the Sierra Nevadas every afternoon at two o'clock and try to blow the town away. The third picture, as you easily perceive, is lightning; its duty was to remind me when it was time to begin to talk about San Francisco weather, where there IS no lightning—nor thunder, either—and it never failed me.

I will give you a valuable hint. When a man is making a speech and you are to follow him don't jot down notes to speak from, jot down PICTURES. It is awkward and embarrassing to have to keep referring to notes; and besides it breaks up your speech and makes it ragged and non-coherent; but you can tear up your pictures as soon as you have made them—they will stay fresh and strong in your memory in the order and sequence in which you scratched them down. And many will admire to see what a good memory you are furnished with, when perhaps your memory is not any better than mine.

Sixteen years ago when my children were little creatures the governess was trying to hammer some primer histories into their heads. Part of this fun--if you like to call it that--consisted in the memorizing of the accession dates of the thirty-seven personages who had ruled over England from the Conqueror down. These little people found it a bitter, hard contract. It was all dates, they all looked alike, and they wouldn't stick. Day after day of the summer vacation dribbled by, and still the kings held the fort; the children couldn't conquer any six of them.

With my lecture experience in mind I was aware that I could invent some way out of the trouble with pictures, but I hoped a way could be found which would let them romp in the open air while they learned the kings. I found it, and then they mastered all the monarchs in a day or two.

The idea was to make them see the reigns with their eyes; that would be a large help. We were at the farm then. From the house-porch the grounds sloped gradually down to the lower fence and rose on the right to the high ground where my small work-den stood. A carriage-road wound through the grounds and up the hill. I staked it out with the English monarchs, beginning with the Conqueror, and you could stand on the porch and clearly see every reign and its length, from the Conquest down to Victoria, then in the forty-sixth year of her reign—eight hundred and seventeen years of English history under your eye at once!

English history was an unusually live topic in America just then. The world had suddenly realized that while it was not noticing the Queen had passed Henry VIII., passed Henry VI. and Elizabeth, and gaining in length every day. Her reign had entered the list of the long ones; everybody was interested now—it was watching a race. Would she pass the long Edward? There was a possibility of it. Would she pass the long Henry? Doubtful, most people said. The long George? Impossible! Everybody said it. But we have lived to see her leave him two years behind.

I measured off 817 feet of the roadway, a foot representing a year, and at the beginning and end of each reign I drove a three-foot white-pine stake in the turf by the roadside and wrote the name and dates on it. Abreast the middle of the porch-front stood a great granite flower-vase overflowing with a cataract of bright-yellow flowers—I can't think of their name. The vase was William the Conqueror. We put his name on it and his accession date, 1066. We started from that and measured off twenty-one feet of the road, and drove William Rufus's stake; then thirteen feet and drove the first Henry's stake; then thirty-five feet and drove Stephen's; then nineteen feet, which brought us just past the summer-house on the left; then we staked out thirty-five, ten, and seventeen for the second Henry and Richard and John; turned the curve and entered upon just what was needed for Henry III.—a level, straight stretch of fifty-six feet of road without a crinkle in it. And it lay exactly in front of the house, in the middle of the grounds. There couldn't have been a better place for that long reign; you could stand on the porch and see those two wide-apart stakes almost with your eyes shut.
