Every bookseller is of necessity a speculator, for it is his business to buy at a low price and to sell at a higher. The amateur, however, should, if he would preserve his title, abstain from traffic of this kind and be satisfied to pay for the privilege of forming a library without regard to the ultimate profit or loss. His pleasure should consist in acquisition and the opportunity afforded of fondling his store while there is time, for he may be absolutely certain that the whole assortment--bookcases, shelves, and all--will find their way to the auctioneer directly he has done with them. This mournful prospect has been the indirect means of founding a new school, that of the semi-amateurs, which, while claiming for itself all the attributes of the book lover, has, nevertheless, an eye to the main chance, and is prepared at a moment's notice to transfer an entire collection _inter vivos_ if the required sum be forthcoming. As an ardent Waltonian would regard a brother of the angle who went a-fishing with the object of selling his catch, so the old-fashioned bibliophile views this degenerate school--that is to say, with unfeigned disgust. It makes no difference, nay, if anything it is an aggravation, that the culprit is "well up" in his subject and knows a book when he sees one. "Fancy!" says a member of the old academy, "here is an educated man who for years has occupied his leisure hours in studies the most delightful, and among friends the most courteous and refined. He knows them, can put his hand upon any in the dark, and yet----;" but here the power of words fails to describe the heartless greed which alone could send a row of life's companions to the block. Nevertheless this is being done every day, and, however vexed the respectable book lover may be, the fact remains that the new school is just now showing remarkable activity and is running the booksellers very close indeed. The advisability of purchasing depends upon the answer to a single question, "Will this book go up?" Never mind the author, or a syllable of what he wrote, but take especial care to see that the work is perfect, clean, and uncut, and then ask yourself this solitary question. This is the first and last commandment of the semi-amateur, whose method of procedure it may be interesting to analyse.
