It was very dull and for the remainder of the month, typical November weather, with what the Trevors called a “pea-soup” atmosphere, deepening now and then into a regular fog. The Square gardens were soaking with moisture, the surrounding houses looked greyer and gloomier than ever, until it seemed impossible to believe that the sky had ever been blue, or that gay-coloured spring flowers had flourished in those black-looking beds.  
and Jill had the bad taste to approve of fogs. They were “ripping,” they declared. “So and jolly! Yesterday, when I was walking to school, a hansom drove on the pavement beside me. Think of that!” cried Jill in a tone of triumph. “The horse’s nose nearly touched my shoulder, and an old lady near me like anything. It was sport!”
 
Jack was rather of the hansom episode, but had had his own share of amusement. “I followed Johnston all the way home, and chaffed him with a in my mouth to disguise my voice. He was nearly mad with rage, and whenever he turned round I simply double, and he went for another fellow, and there was no end of a game.”
 
“But how did it happen that you could see him when he couldn’t see you?” Jill, when Jack was forced to admit that he had made mistakes more than once; but it only added to the sport to see the of innocent when an accusing voice suddenly in their ears, “Who the indiarubber from Smith’s desk?”
 
The twins were happily constituted to enjoy all things, and from their conversation it would have appeared that to be hopelessly lost in a fog would be the of earthly joy; but Betty hated the gloom of the long days, when the gas burned from breakfast to bedtime, and was nervous about trusting herself alone in the streets. In her leisure moments she herself to the preparation of Christmas presents, and turned over the contents of her scrap-drawers, debating how to make a dozen handsome articles with the least possible . It is to be feared that Betty’s gifts were arranged more to suit her own convenience than the tastes of the . “This will make a book-cover for Jill. I don’t suppose she’ll ever use it, but it’s not big enough for anything else, so she’ll just have to like it!” This was the spirit in which she her materials, and set to work thereon. Not the ideal attitude by any means, but one must make allowances for a girl with a small allowance and a large family connection, and must also enter it to the credit of this particular damsel that she no work which could beautify the simple background. Poor Betty! For two whole gloomy afternoons did she work at a spray of roses on a work-bag, and on the third day a feeble gleam of sunlight showed itself, and lo, the roses were a harlequin study in pinks and orange!
 
“Is it at all trying? Is it enough to make you pitch the whole thing into the fire?” she demanded dramatically of the chairs and tables, as the horrible discovery burst upon her, and she proceeded to snap at the silk with her sharp little scissors, and viciously tear away the stitches. “Shan’t bother to fill them in any more! They’ll just have to do in outline, and if she doesn’t like it she can do the other thing!” she under her breath; but that was only the impulse of the moment, and when it came to action each stitch was put in as carefully as before.
 
“What are you sewing away at those old things for?” Jill demanded, coming into the room and seating herself easily on the edge of the table. “It’s much easier to buy match-boxes and needle-books. You can get beauties for sixpence three-farthings at the Christmas , and it saves no end of fag. You can give me safety-pins if you like, for my clothes are all coming to pieces, and my pins disappear like smoke. Mary eats them, I believe! What are you going to give mother?”
 
“Can’t think! She wants a palm for the drawing-room, but a nice one costs half a guinea, and I couldn’t possibly scrape together more than three and six.”
 
Jill pondered, swinging her feet to and fro. “Five more Saturdays at fourpence each,—one and eight-pence, and I’ve got about two shillings in hand. No! I couldn’t possibly offer to join. I wish we could have managed it, for the drawing-room doesn’t look half furnished, and a big palm would have made a fine effect, but we can’t, so there’s an end of that!”
 
A of suppressed nervousness sounded from the end of the room, and Pam’s voice said with the usual funny little , “I’ve got sixpence with a hole in it. I’ll join, Betty! Do get mother a palm! She wants it so badly. We saw one in a shop window yesterday, and she said it was just the thing for our room!”
 
“Sorry, Pam, but it can’t be done. They are a price in the shops, and even old ‘All a-growing all a-blowing’ has none under seven and six. Perhaps when her birthday comes round we can manage it, but at Christmas there are so many presents to buy that one can’t afford big things.”
 
“I want to get it now,” Pam , while Jill jumped down from the table and turned to the door.
 
“I’m going out! Can’t afford to waste holiday afternoons. Why don’t you put away that stupid work and come too?”
 
“Where are you going? A walk?”
 
“Rather not! Am I a Pet to up and down? Jack and I are going to have some fun in the Square. I’m not going to tell you what it is, but you can come too if you like.”
 
Betty raised her head and peered out of the window. Black railings, black trees, grass, paths strewn with decaying leaves, a fast-failing light. She gave a of distaste and sank back in her chair.
 
“Thanks! I prefer the fire. I can’t understand you, Jill, going in for an exam, and wasting every spare moment you get! When I went in, I every Saturday afternoon the whole term, and never dreamed of going out.”
 
“Yes, and got plucked for your pains!” retorted Jill . Poor Betty! She had passed so well in everything but that fatal arithmetic, which made all the difference between success and failure. The figures would not add up, the lines danced before her eyes, she could not remember the simplest table. It was cruel to rake up that old sore. She pressed her lips together and sat in offended dignity, while Jill skipped to the door, tossing her pretty pert head.
 
“I shall take care of my health and my nerves, and not have them breaking down just when I need them most. If the worst comes to the worst, I shall be no worse off than you were yourself, and I shall have had my fun!”
 
She ran downstairs into the hall, where Jack was awaiting her with a brown-paper parcel tucked under his arm, and together they crossed the road to the nearest gate, and let themselves into the garden with a heavy key.
 
“The other corner is the best,” Jack cried, leading the way forward at an eager pace, “more traffic, and thicker bushes. I the exact place yesterday. Have you got the reel in your pocket all right?”
 
“Yes, yes! And you must give me my turn, Jack. It’s only fair, because you wouldn’t let me have a parcel of my own on the other side.”
 
“Of course not! You wouldn’t expect to find two lost parcels within a few yards of each other, would you? You want to give the whole show away!” cried Jack in indignant schoolboy fashion. “Now don’t talk so much, but creep between these bushes when nobody is passing. There’s room for us both, and I can get a pull at the string between these branches. We’ll have a now, and see how it works.” He crawled forward on the dank earth, in easy unconcern for the knees of his trousers, dropped the daintily-wrapped parcel on to the centre of the pavement, and crept back to his place, holding in his hand the end of a long black thread.
 
They together behind the bushes, as a Jack and Jill as have been known since the world began, with anticipated glee, nudging each other violently at the sound of approaching footsteps, and peering eagerly through their loopholes to see what manner of was about to fall into their hands.
 
First, a fine lady walking gingerly along, both hands occupied in keeping her skirt from contact with the pavement. She looked at the parcel with blank , and passed quietly on her way. The twins with stupefaction. Could such things be? Was it possible that a human creature could be so with the good things of this world, that she could an unopened parcel lying on the ground, and feel no curiosity to discover what was inside? Imagination refused to picture such a position!
 
“Mad!” was Jack’s scornful explanation. “Mad as a March hare! Ought to be shut up out of the way. Walked straight over the string too. Hope to goodness she hasn’t broken it!”
 
A to the end of the string proved that this fear was unfounded, and the twins composed themselves for another period of waiting. Pedestrians seemed to prefer the pavement by the houses instead of that darker one overshadowed by the trees of the gardens, and several moments elapsed before a brisk footstep announced the approach of a tall, well set-up man clad in a light overcoat. His eye lit on the parcel, he bent his head and stretched out a hand to raise it up. Instantly Jack gave a flick to the string, to which the parcel responded by jumping an inch or two farther along the pavement. The brown-coated man straightened himself, gave a funny little , half amused, half-angry, and strode on his way. He had been a boy himself!
 
The next victim was an old woman carrying a pile of parcels, and breathing heavily from , but although over-laden, she was evidently nothing to add to her burden. The twins could hear her surprised , and see the of the shoulders with which she freed her right arm for the attack. Down she bent, panting louder than before, until, even as her envious fingers approached the prize, it leapt into the air, and as by some magic process disappeared from sight. Jack was bursting with pride at his own , and Jill nudged in enthusiastic approval. This came of fishing by the river-banks in the last summer holidays, and gaining in the art of casting lines! It was wonderful how useful such were at times. The bewildered face of the disappointed treasure-seeker was almost too much for the , and had she not been too much in her own thoughts she must certainly have heard the splutterings which not even the handkerchief stuffed between Jill’s lips could drown. With a sigh she went on her way, wondering if eyesight were about to fail, as the of her troubles.
 
After this came an errand-boy, whistling as he walked. He made a at the parcel, and when it disappeared had no difficulty in understanding the phenomenon.
 
“Ho, you would, would you?” he cried, and picking up a handful of stones, sent them flying in among the bushes with such force that the twins congratulated themselves on escaping without injury.
 
They learnt a lesson from this experience, and henceforth made a rule of allowing all boys to pass by when they practised this particular pastime. By this time Jill was shivering in her shabby coat, and beginning to cast glances across the Square to the lighted schoolroom window. of tea and hot buttered toast—the Saturday afternoon treat of years’ standing—made her present position seem unattractive, and she proposed an home.
 
Jack, however, was not yet satisfied with his achievements.
 
“We haven’t had what I call a real proper rise out of anyone yet. Just once more, and then we’ll run for it,” he protested, and Jill shivered, and yielded to his superior will.
 
She had not long to wait. In less than five minutes a slow, measured tread was heard in the distance, and presently an elderly gentleman hove in sight, portly, well-dressed, and walking with a certain stiffness and deliberation which would have secured for him the sympathetic consideration of people of his own age. Jack and Jill, however, had no thought for such uninteresting subjects as ; they nudged each other delightedly, and waited in breathless silence to see what would happen next.
 
Tramp, tramp, tramp came the slow approach, and then a sudden halt—the halt they knew so well—followed by something like a as the victim stiffly bent forward to examine the treasure-trove. His gloved hand had nearly closed on the parcel when Jack it a few inches away. He bent still farther, with another effort, and then, even as the parcel again moved , there came a loud, startled cry, and the twins their victim fall forward on his face, and lie helpless on the ground.
