Many a journeyman has broken up his narrative and skipped about and rambled around, but he did it for a purpose, for an advantage; there was art in it, and points to be scored by it; the observant reader perceived the game, and enjoyed it and respected it, if it was well played.

But Mrs.Eddy's performance was without intention, and destitute of art.

She could score no points by it on those terms, and almost any reader can see that her work was the uncalculated puttering of a novice.
In the above paragraph I have described the first third of the booklet.
That third being completed, Mrs.Eddy leaves the rabbit-range, crosses the frontier, and steps out upon her far-spreading big-game territory--Christian Science and there is an instant change! The style smartly improves; and the clumsy little technical offenses disappear.

In these two-thirds of the booklet I find only one such offence, and it has the look of being a printer's error.
I leave the riddle with the reader.

Perhaps he can explain how it is that a person-trained or untrained--who on the one day can write nothing better than Plague-Spot-Bacilli and feeble and stumbling and wandering personal history littered with false figures and obscurities and technical blunders, can on the next day sit down and write fluently, smoothly, compactly, capably, and confidently on a great big thundering subject, and do it as easily and comfortably as a whale paddles around the globe.
As for me, I have scribbled so much in fifty years that I have become saturated with convictions of one sort and another concerning a scribbler's limitations; and these are so strong that when I am familiar with a literary person's work I feel perfectly sure that I know enough about his limitations to know what he can not do.
