напишите пожалуйста краткий пересказ текста the story of Merrymind 7:
"Once upon a time there lived in the north country a certain poor man and his wife, who had two corn-fields, three cows, five sheep, and thirteen children. Twelve of these children were called by names common in the north country—Hardhead, Stiffneck, Tightfingers, and the like; but when the thirteenth came to be named, either the poor man and his wife could remember no other name, or something in the child's look made them think it proper, for they called him Merrymind, which the neighbours thought a strange name, and very much above their station; however, as they showed no other signs of pride, the neighbours let that pass. Their thirteen children grew taller and stronger every year, and they had hard work to keep them in bread; but when the youngest was [178] old enough to look after his father's sheep, there happened the great fair, to which everybody in the north country went, because it came only once in seven years, and was held on midsummer-day,—not in any town or village, but on a green plain, lying between a broad river and a high hill, where it was said the fairies used to dance in old and merry times.
"Merchants and dealers of all sorts crowded to that fair from far and near. There was nothing known in the north country that could not be bought or sold in it, and neither old nor young were willing to go home without a fairing. The poor man who owned this large family could afford them little to spend in such ways; but as the fair happened only once in seven years, he would not show a poor spirit. Therefore, calling them about him, he opened the leathern bag in which his savings were stored, and gave every one of the thirteen a silver penny.
"The boys and girls had never before owned so much pocket-money; and, wondering what they should buy, they dressed themselves in their holi- [179] day clothes, and set out with their father and mother to the fair. When they came near the ground that midsummer morning, the stalls, heaped up with all manner of merchandise, from ginger-bread upwards, the tents for fun and feasting, the puppet-shows, the rope-dancers, and the crowd of neighbours and strangers, all in their best attire, made those simple people think their north country fair the finest sight in the world. The day wore away in seeing wonders, and in chatting with old friends. It was surprising how far silver pennies went in those days; but before evening twelve of the thirteen had got fairly rid of their money. One bought a pair of brass buckles, another a crimson riband, a third green garters; the father bought a tobacco-pipe, the mother a horn snuffbox—in short, all had provided themselves with fairings except Merrymind.
"The cause of the silver penny remaining in his pocket was that he had set his heart upon a fiddle; and fiddles enough there were in the fair—small and large, plain and painted; he looked at and priced the most of them, but there was not one [180] that came within the compass of a silver penny. His father and mother warned him to make haste with his purchase, for they must all go home at sunset, because the way was long.
