One of the great defects of English books printed in the last century is the want of an index. The importance of being able to refer at once to any subject treated of in a book was not recognized until the days when exact scholarship necessitated indexing of the most elaborate kind. But even now we constantly find good books severely criticized because of this deficiency. All that I have said tends to show that even to-day in Western countries the immense importance of systematic arrangement in literary collections is not sufficiently recognized. We have, of course, a great many English anthologies,--that is to say, collections of the best typical compositions of a certain epoch in poetry or in prose. But you must have observed that, in Western countries, nearly all such anthologies are compiled chronologically--not according to the subject of the poems. To this general rule there are indeed a few exceptions. There is a collection of love poetry by Watson, which is famous; a collection of child poetry by Patmore; a collection of "society verse" by Locker-Lampson; and several things of that sort. But even here the arrangement is not of a special kind; nor is it ever divided according to the subject of each particular poem. I know that some books have been published of late years with such titles as "Poems of the Sea," "Poems of Nature"--but these are of no literary importance at all and they are not compiled by competent critics. Besides, the subject-heads are always of much too general a kind. The French are far in advance of the English in the art of making anthologies; but even in such splendid anthologies as those of Crépet and of Lemerre the arrangement is of the most general kind,--chronological, and little more.
