UXOLE W1CGIRY AND Till", nui: STOXK.

Nure Jane Fuzzy Wuzzy. the musk-rat lady housekeeper, one day came around the corner of the hollow stump bur.?a!ox, walking on the shady porch. In her paws Nurse Jane clicked a pIr of scissor. "Oh. ho! No. you don"t: N'o. you don't, if you please!" cried Unncle Wigrily. leaplnsr up frcm the eny chair, where he was rltilr.sr. "I can't let you do It. Nurse Jane!" "Do it! Do what?" the mu?krat !ady wanted to know with a em!. as h kept on clicking the seizor. "Don't you war.t to do. me a favor, Uncle WirsMy?" "Of coure, I do." annvered the rabbit gentleman, "but I can't let you cut my hair. The last time you did it I looked so funny that even Grandfather Gooey Gander laughed. If I need my hair cut I'm polr.gr to the regular barber. I'd rather you wouldn't do it." "Why. I'm not goJn? to cut your hair!" laughed Nurse Jane. "You aren't?" cried th bunny.

"Then why do you come arm with C'.iCk;nc sc'.wors?"' "I Ju.at want you to tikN my ahear to the grinder's and set them shnrpene' .P0!;e th mu-krat lidy. "They aro P0 du, thpv VPn-t cu cloth. and the s?issor-sharpener monkey hasn't beer, alor? thts week. Ju.". take my shear to the tinker's and have him srrir.d them sharp; will you. Uncle Wiretly?" "I w-ill." pronved the bunny uncle gentleman, with a twinkle of h! p'.nk nose. "And on the way there I may have an adventure." "Well, be careful you don't fall down and utick yourMlf on the harp points of the feasors," begged Nur Jane. -The points art eharp enough, even if the edces are to duli they won't cut cloth." "I'll be careful." aid I'ncle W!ffgily, and away h hopped, over the fitlds and through the woods. He had not gone very fir before, all of a sudden, goinr dwn a hill that was covered with j tones, the bunny flipped and fell. "Oh. I must be careful not to nick myself with the .clssor?!" he thought, and he held them out in front of hlmas he tumbled down. All Of a sudden, as he fell kerbunkO, Uncle Wiggily ?aw a lot of fiery ppark. which seemed to come from his paw tht hld Nurs Jane's ehear. "Dear me! What's that?" thought the bunny gentleman. "I that ÜShtninp? I didn't hear anv thun-

der! I wonfef if I'm turned?' H ecra.mbled to his fet and locked at the paw that hJd the fri.-or. It wasn't burned, nor was there ir.y s:j:n of f.re. "Yet I pi v. spark come right out 'f the grourd!" aid the rabbit. "I wor.der how it happened? Mayb there a Ml fairy arouni hre who will turn me into & butterfly, or something like that." "Hat IIa! Hat" laughed a little voice down on the ground. "Oh. ore you a fairy?" afked Uncle W:ggi!y. getting re.ady to run. "No. mde-?d. was the answer. "I am a little black ant lady. But it makes me laugh to hear you say perhaps the sparks were caused by a fairy. You mde the f.re spark yourself." "I did? How?" asked Uncle Wigglly, looking at the steel c:sors. "When yu fell." explained the ant Isdv. "Nurse Jane's sr-iors struck on the Are stcne, and sparks came forth." What'. a fire stone?" asked the bunr.y. wonderingly. "There it is." ar.fwerei the ar.t 3idy. pointi:?: to a black stone on the path where Uncle Wiggily had stumbled. 'That's the fire f-tor.e." "But I don't se any sparks cominp out of it now," spoke the bunny. "No. it is only when you strike a piece of fire stone, or flint, with a piece of steel that spark. com forth." explained the ant lady.

"The Are ton la ary hard, much h?.rder than th el In Nurse Jin's seizors. And when -ej siruck th sc.f.r on the hard sto(ie so;r. little crumby of steel were f:rApl off. Ar.d they came off e fist that thy were heated rd hM. .".nd that's what rr.a! the pirk" "Oh. it's like Fourth cf July fireworks!"' cr:ed Uncle Wipg.ly In delisht "Do you suppose I could do it .aeain?" "Why. of ccurse," a-d the ant lady. Po Uncle Wics'dy held the cienrs in h: paw. and struck the back edge a c'.ncing blow on the h"rd flint or Are stone. At once a shower of sparks scattered around. "Taat's how they made fire in the old day.." explained the ant lady, "with flint and steel, and how they used to shoot guns the flint lock muskets. But now I must hurry home." "Thank you for telling m abut the Are stone." aid Uncle Wiggily. "I'm going to take it with me." And he did. And n little later the Furry Fox chase! the bunny. Rut UnCle Wijrsrily just to-k out the flre Fton. made a lot of spark come from th scissors, and the Fox was s frightened that he ran away without nib hllr.s the bunny gentleman's cars. Then Uncle WigRily took Nurs Jane' scissors to be sharpened, and he had carrot shortcake fcr supper. Ar.d if the fire shovel doesn't go to sleep ;n the ice wagon and catch
