So they did begin, and went on, interrupted only by Baby Rose's coos and splutters till the dusk fell, till appetizing smells floated through from the rear of the house, and the click of a latch key announced Mr Browne, come home just in time for dinner.

The two days' visit went only too quickly. There is nothing more fascinating to a girl than the menage of a young couple of her own age. It is a sort of playing at real life without the cares and the sense of responsibility that real life is sure to bring. Rose was an adventurous house-keeper. She was still new to the position; she found it very entertaining, and she delighted in experiments of all sorts. If they turned out well, it was good fun; if not, that was funnier still! Her husband, for all his serious manner, had a real boy's love of a lark, and he aided and abetted her in all sorts of whimsical devices. They owned a dog who was only less dear than the baby, a cat only less dear than the dog, a parrot whose education required constant supervision, and a hutch of ring doves whose melancholy little `whuddering' coos were the delight of Rose. The house seemed astir with young life all over. The only elderly thing in it was the cook, who had the reputation of a dreadful temper; only unfortunately, Rose made her laugh so much that she never found time to be cross.

Katy felt quite an old, experienced person amid all this movement and liveliness and cheer. It seemed to her that nobody in the world could possibly be having such a good time as Rose; but Rose did not take the same view of the situation.

`It's all very well now,' she said, `while the warm weather lasts, but in winter Longwood is simply gruesome. The wind never stops blowing day or night. It howls and it roars and it screams, till I feel as if every nerve in my body were on the point of snapping in two. And the snow, ugh! And the wind, ugh! And burglars! Every night of our lives they come - or I think they come - and I lie awake and hear them sharpening their tools and forcing the locks and murdering the cook and kidnap-ping Baby, till I long to die and have done with them forever! O, nature is the most unpleasant thing!'

`Burglars are not nature,' objected Katy.

`What are they, then? Art? High art? Well, whatever they are, I do not like them. Oh, if ever the happy day comes when Deniston consents to move into town, I never wish to set my eyes on the country again as long as I live, `unless - well, yes, I should like to come out just once more in the horse-cars and kick that elm tree by the fence! The number of times that I have lain awake at night listening to its creaking!'

`You might kick it without waiting to have a house in town.

`Oh, I shouldn't dare as long as we are living here! You never know what nature may do. She has ways of her own of getting even with people,' remarked her friend, solemnly.

No time must be lost in showing Boston to Katy, Rose said. So, the morning after her arrival she was taken in bright and early to see the sights. There were not quite so many sights to be seen then as there are today. The Art Museum had not got much above its foundations; the new Trinity Church was still in the future; but the big organ and the bronze statue of Beethoven were in their glory, and every day at high noon a small straggling audience wandered into the Music Hall to hear the instrument played. To this extempore concert Katy was taken, and to Faneuil Hall and the Athenaeum, to Doll and Richards, where was an exhibition of pictures, to the Granary Graveyard, and the Old South. Then the girls did a little shopping, and by that time they were quite tired enough to make the idea of luncheon agreeable, so they took the path across the Common to the Joy Street Mall.

Katy was charmed by all she had seen. The delightful nearness of so many interesting things surprised her. She perceived what is one of Boston's chief charms - that the Common and its surrounding streets make a natural centre and rallying point for the whole city, as the heart is the centre of the body and keeps up a quick correspondence and regulates the life of all its extremities. The stately old houses on Beacon Street, with their rounded fronts, deep window casements, and here and there a mauve or a
