Not that dramatic, still less didactic, intention should disqualify a work of art for museum purposes. But--broadly--dramatic and didactic art should be universally national, the luster of our streets, the treasure of our palaces, the pleasure of our homes. Much art that is weak, transitory, and rude may thus become helpful to us. But the museum is only for what is eternally right, and well done, according to divine law and human skill. The least things are to be there--and the greatest--but all _good_ with the goodness that makes a child cheerful and an old man calm; the simple should go there to learn, and the wise to remember. 213. And now to return to what I meant to be the subject of this letter--the arrangement of our first ideal room in such a museum. As I think of it, I would fain expand the single room, first asked for, into one like Prince Houssain's,--no, Prince Houssain had the flying tapestry, and I forget which prince had the elastic palace. But, indeed, it must be a lordly chamber which shall be large enough to exhibit the true nature of thread and needle--omened in "Thread-needle Street!" The structure, first of wool and cotton, of fur, and hair, and down, of hemp, flax, and silk:--microscope permissible if any cause can be shown _why_ wool is soft, and fur fine, and cotton downy, and down downier; and how a flax fiber differs from a dandelion stalk, and how the substance of a mulberry leaf can become velvet for Queen Victoria's crown, and clothing of purple for the housewife of Solomon. Then the phase of its dyeing. What azures, and emeralds, and Tyrians scarlets can be got into fibers of thread. 214. Then the phase of its spinning. The mystery of that divine spiral, from finest to firmest, which renders lace possible at Valenciennes--anchorage possible, after Trafalgar--if Hardy had but done as he was bid. Then the mystery of weaving. The eternal harmony of warp and woof, of all manner of knotting, knitting, and reticulation, the art which makes garment possible, woven from the top throughout, draughts of fishes possible, miraculous enough in any pilchard or herring shoal, gathered into companionable catchableness;--which makes, in fine, so many Nations possible, and Saxon and Norman beyond the rest. 215. And finally, the accomplished phase of needlework, the _Acu Tetigisti_ of all time, which does, indeed, practically exhibit what mediaeval theologists vainly tried to conclude inductively--How many angels can stand on a needle-point. To show the essential nature of a stitch--drawing the separate into the inseparable, from the lowly work of duly restricted sutor, and modestly installed cobbler, to the needle-Scripture of Matilda, the Queen.
