Gossip Pietro, whose wit was somewhat blunt, believed that ’twas as she said, approved her counsel, and began adjuring Dom Gianni, as persuasively as he might, to teach him the incantation.  Dom Gianni did his best to wean him of his folly; but as all was in vain:—­“Lo, now,” quoth he, “as you are both bent on it, we will be up, as is our wont, before the sun to-morrow morning, and I will shew you how ’tis done.  The truth is that ’tis in the attachment of the tail that the great difficulty lies, as thou wilt see.”  Scarce a wink of sleep had either Gossip Pietro or Gossip Gemmata that night, so great was their anxiety; and towards daybreak up they got, and called Dom Gianni; who, being risen, came in his shirt into Gossip Pietro’s little bedroom, and:—­“I know not,” quoth he, “that there is another soul in the world for whom I would do this, save you, my gossips; however, as you will have it so, I will do it, but it behoves you to do exactly as I bid you, if you would have the enchantment work.”  They promised obedience, and Dom Gianni thereupon took a light, which he handed to Gossip Pietro, saying:—­“Let nought that I shall do or say escape thee; and have a care, so thou wouldst not ruin all, to say never a word, whatever thou mayst see or hear; and pray God that the tail may be securely attached.”  So Gossip Pietro took the light, and again promised obedience; Dom Gianni caused Gossip Gemmata to strip herself stark naked, and stand on all fours like a mare, at the same time strictly charging her that, whatever might happen, she must utter no word.  Then, touching her head and face:—­“Be this a fine head of a mare,” quoth he; in like manner touching her hair, he said:—­“Be this a fine mane of a mare;” touching her arms:—­“Be these fine legs and fine hooves of a mare;” then, as he touched her breast and felt its firm roundness, and there awoke and arose one that was not called:—­“And be this a fine breast of a mare,” quoth he; and in like manner he dealt with her back, belly, croup, thighs, and legs.  Last of all, the work being complete save for the tail, he lifted his shirt and took in his hand the tool with which he was used to plant men, and forthwith thrust it into the furrow made for it, saying:—­“And be this a fine tail of a mare.”  Whereat Gossip Pietro, who had followed everything very heedfully to that point, disapproving that last particular, exclaimed:—­“No!  Dom Gianni, I’ll have no tail, I’ll have no tail.”  The essential juice, by which all plants are propagated, was already discharged, when Dom Gianni withdrew the tool, saying:—­“Alas!  Gossip Pietro, what hast thou done?  Did I not tell thee to say never a word, no matter what thou mightst see?  The mare was all but made; but by speaking thou hast spoiled all; and ’tis not possible to repeat the enchantment.”  “Well and good,” replied Gossip Pietro, “I would have none of that tail.  Why saidst thou not to me:—­’Make it thou’?  And besides, thou wast attaching it too low.” “’Twas because,”
