ago, and now, I have no doubt, there are dozens of monographs on the flowers that flourish there. Indeed, there is not a thing that grows that may not furnish a monograph. The author spends perhaps twenty years in collecting his material, during which time he must of course come across a great variety of amusing information, and then he spends another ten years writing out a fair copy of his labours. Then he thinks it does not quite do in that form, so he snips a paragraph out of the beginning and puts it at the end; next he shifts some more matter from the middle to the preface; then he thinks it over. It seems to him that it is too big, it wants condensation. The scientific world will say he has made too much of it; it ought to read very slight, and present the facts while concealing the labour. So he sets about removing the superfluous--leaves out all the personal observations, and all the little adventures he has met with in his investigations; and so, having got it down to the dry bones and stones thereof and omitted all the mortar that stuck them together, he sends for the engraver, and the next three years are occupied in working up the illustrations. About this time some new discovery is made by a foreign observer, which necessitates a complete revision of the subject; and so having shifted the contents of the book about hither and thither till he does not know which is the end and which is the beginning, he pitches the much-mutilated copy into a drawer and turns the key. Farewell, no more of this; his declining days shall be spent in peace. A few months afterwards a work is announced in Leipsic which 'really trenches on my favourite subject, and really after spending a lifetime I can't stand it.' By this time his handwriting has become so shaky he can hardly read it himself, so he sends in despair for a lady who works a type-writer, and with infinite patience she makes a clean manuscript of the muddled mass. To the press at last, and the proofs come rapidly. Such a relief! How joyfully easy a thing is when you set about it! but by-and-by this won't do. Sub-section A ought to be in a foot-note, family B is doubtful; and so the corrections grow and run over the margin in a thin treble hand, till they approach the bulk of the original book--a good profit for the printer; and so after about forty years the monograph is published--the work of a life is accomplished. Fifty copies are sent round to as many public libraries and learned societies, and the rest of the impression lies on the shelves till dust and time and spiders' webs have buried it. Splendid work in it too. Looked back upon from to-day with the key of modern thought, these monographs often contain a whole chest of treasure. And still there are the periodicals, a century of magazines and journals and reviews and notices that have been coming out these hundred years and dropping to the ground like dead leaves unnoticed. And then there are the art
