+A Great Change
+
+
+"There's no doubt about it, we really must economize somehow!" sighed
+Mrs. Woodward helplessly, with her housekeeping book in one hand, and
+her bank pass-book in the other, and an array of bills spread out on the
+table in front of her. "Children, do you hear what I say? The war will
+make a great difference to our income, and we can't--simply _can't_--go
+on living in exactly the old way. The sooner we all realize it the
+better. I wish I knew where to begin."
+
+"Might knock off going to church, and save the money we give in
+collections!" suggested Percy flippantly. "It must tot up to quite a
+decent sum in the course of a year, not to mention pew rent!"
+
+His mother cast a reproachful glance at him.
+
+"Now, Percy, _do_ be serious for once! You and Winona are quite old
+enough to understand business matters. I must discuss them with
+somebody. As I said before, we shall really have to economize somehow,
+and the question is where to begin."
+
+"I saw some hints in a magazine the other day," volunteered Winona,
+hunting among a pile of papers, and fishing up a copy of _The
+Housewife's Journal_. "Here you are! There's a whole article on War
+Economies. It says you can halve your expenses if you only try. It gives
+ten different recipes. Number One, Dispense with Servants. Oh, goody! I
+don't know how the house would get along without Maggie and Mary! Isn't
+that rather stiff?"
+
+"It's impossible to be thought of for a moment! I should never dream of
+dismissing maids who have lived with me for years. I've read that
+article, and it may be practicable for other people, but certainly not
+for us. Oh, dear! Some of my friends recommend me to remove to the town,
+and others say 'Stay where you are, and keep poultry!'"
+
+"We can't leave Highfield! We were all born here!" objected Winona
+decisively.
+
+"And we tried keeping hens some time ago," said Percy. "They laid on an
+average three-quarters of an egg a year each, as far as I remember."
+
+"I'm afraid we didn't know how to manage them," replied Mrs. Woodward
+fretfully. "Percy, leave those papers alone! I didn't tell you to turn
+them over. You're mixing them all up, tiresome boy! Don't touch them
+again! It's no use trying to discuss business with you children! I shall
+write and consult Aunt Harriet. Go away, both of you, now! I want to
+have a quiet half-hour."
+
+Aunt Harriet stood to the Woodward family somewhat in the light of a
+Delphic oracle. To apply to her was always the very last resource.
+Matters must have reached a crisis, Winona thought, if they were
+obliged to appeal to Aunt Harriet's judgment. She followed Percy into
+the garden with a sober look on her face.
+
+"You don't think mother would really leave Highfield?" she asked her
+brother anxiously.
+
+"Bunkum!" replied that light-hearted youth. "We always have more or less
+of a fuss when my school bills come in. It'll soon fizzle out again!
+Don't you fret yourself. Things will jog on as they always have jogged
+on. There'll be nothing done, you'll see. Come on and bowl for me,
+that's a chubby one!"
+
+"But this time mother really seemed to be in earnest," said Winona
+meditatively, as she helped to put up the stumps.
+
+Mrs. Woodward had been left a widow three years before this story opens.
+She was a fair, fragile little woman, still pretty, and pathetically
+helpless. She had been accustomed to lean upon her husband, and now, for
+lack of firmer support, she leaned upon Winona. Winona was young to act
+as prop, and though it flattered her sense of importance, it had put a
+row of wrinkles on her girlish forehead. At fifteen she seemed much
+older than Percy at sixteen. No one ever dreamt of taking Percy
+seriously; he was one of those jolly, easy-going, happy-go-lucky,
+unreliable people who saunter through life with no other aim than to
+amuse themselves at all costs. To depend upon him was like trusting to a
+boat without a bottom. Though nominally the eldest, he had little more
+sense of responsibility than Ernie, the youngest. It was Winona who
+shouldered the family burdens.
+
+The Woodwards had always lived at Highfield, and in their opinion it was
+the most desirable residence in the whole of Rytonshire. The house was
+old enough to be picturesque, but modern enough for comfort. Its quaint
+gables, mullioned windows and Cromwellian porch were the joy of
+photographers, while the old-fashioned hall, when the big log fire was
+lighted, would be hard to beat for coziness. The schoolroom, on the
+ground floor, had a separate side entrance on to the lawn, leading
+through a small ante-room where boots and coats and cricket bats and
+tennis rackets could be kept; the drawing-room had a luxurious ingle
+nook with cushioned seats, and all the bedrooms but two had a southern
+aspect. As for the big rambling garden, it was full of delightful
+old-world flowers that came up year after year: daffodils and violets
+and snow-flakes, and clumps of pinks, and orange lilies and Canterbury
+bells, and tall Michaelmas daisies, and ribbon grass and royal Osmunda
+fern, the sort of flowers that people used to pick in days gone by, put
+a paper frill round, and call a nosegay or a posy. There was a lawn for
+tennis and cricket, a pond planted with irises and bulrushes, and a wild
+corner where crocuses and coltsfoot and golden aconite came up as they
+liked in the spring time.
+
+Winona loved this garden with somewhat the same attachment that a French
+peasant bears for the soil upon which he has been reared. She rejoiced
+in every yard of it. To go away and resign it to others would be
+tragedy unspeakable. The fear that Aunt Harriet might recommend the
+family to leave Highfield was sufficient to darken her horizon
+indefinitely. That her mother had written to consult the oracle she was
+well aware, for she had been sent to post the letter. She had an
+instinctive apprehension that the answer would prove a turning-point in
+her career.
+
+For a day or two everything went on as usual. Mrs. Woodward did not
+again allude to her difficulties, Percy had conveniently forgotten them,
+and the younger children were not aware of their existence. Winona lived
+with a black spot dancing before her mental eyes. It was continually
+rising up and blotting out the sunshine. On the fourth morning appeared
+a letter addressed in an old-fashioned slanting handwriting, and bearing
+the Seaton post mark. Mrs. Woodward read it in silence, and left her
+toast unfinished. Aunt Harriet's communications generally upset her for
+the day.
+
+"Come here, Winona," she said agitatedly, after breakfast. "Oh, dear, I
+wish I knew what to do! It's so very unexpected, but of course it would
+be a splendid thing for you. If only I could consult somebody! I suppose
+girls nowadays will have to learn to support themselves, and the war
+will alter everything, but I'd always meant you to stop at home and look
+after the little ones for me, and it's very--"
+
+"What does Aunt Harriet say, mother?" interrupted Winona, with a catch
+in her throat.
+
+"She says a great deal, and I dare say she's right. Oh, this terrible
+war! Things were so different when I was a girl! You might as well read
+the letter for yourself, as it concerns you. I always think she's hard
+on Percy, poor lad! I was afraid the children were too noisy the last
+time she was here, but they wouldn't keep quiet. I'm sure I try to do my
+best all round, and you know, Winona, how I said Aunt Harriet--"
+
+But Winona was already devouring the letter.
