"I am going to study there, too, some day, like father and Uncle Clarke, and be a great doctor," said Don. "I thought you were going to be a piper a little while ago," laughed Sandy. "And it was a 'herd' you were going to be just the other day," echoed Marjorie. "I don't care," retorted Don, stoutly, "I am going to do something great, anyway." "That's the right spirit, my son; whatever you do, do it well," said his father, patting him on the shoulder. The children laughed, but his father was very pleased. CHAPTER IV. ANOTHER WALK IN EDINBURGH AND A VISIT TO ABBOTSFORD "THE lassies are going with me to do a bit of shopping in Princes Street," said Mrs. Gordon, as they all sat around the breakfast-table one morning. "We want to buy a present for mother's birthday while we are here. It is week after next, you know," said Janet. "I don't suppose you want to go with us, Don; lads don't like to buy things," she added, with a twinkle in her eye. "Oh! Well, if you are only going after trinkets, I wouldn't give a 'bawbee' for that kind of fun. Now, if you were really going to _see_ things, that might be different," said Donald, eagerly. "You have not seen the 'Dog's Monument,' and lots of things yet," he continued, thinking it a little beneath his dignity to go shopping, but in his heart really wishing to go, if only he were begged hard enough. "No one can tell the story of the faithful dog better than Don, so you lassies ought to get him to show you his grave and that of his master," said the doctor, who saw Don's trouble, and was ready to help him out. Of course this made the little girls wild to hear all about it, so Don had to promise to go with them and show them the spot. It did not take long to reach Princes Street, which the Scotch people think the finest street in the world. It is a splendid broad thoroughfare; on one side are the beautiful "Gardens," with flowers, statues, and walks, while rising high above is the old castle on its height. On the other side of the street are the great shops and hotels. The shops are full of pretty Scotch things. There you may see all the different kinds of "Clan" tartans, and there are a great many of them. There also are heaps of "cairngorms" and purple amethysts, which is another precious stone found in Scotland, and is almost as much of a favourite as the "cairngorms." Both of these stones were much used to ornament the ancient Scotch swords and daggers, and were often set into brooches used to fasten the tartans, as you see in the piper's picture. The jewellers now make them up into all kinds of souvenirs of Scotland; little claymores and daggers for pins, and copies of old-time brooches, and all kinds of quaint things. "Well, dearies, what do you think your mother would like?" asked Mrs. Gordon, as they passed by the gay shops.
