In a thousand ways Walter showed his love of history and romance. Anything that was picturesque, whether it was a view or an old dirk, caught his attention at once. For a short time he took lessons in oil painting from a German. He soon found that he had not the eye nor the hand for the work, but it happened that the teacher's father had been a soldier in the army of Frederick the Great, and as soon as Walter found this out, he plied the man with questions. Long afterward he said he vividly remembered the man's picturesque account of seeing a party of the famous Black Hussars bringing in forage carts which they had captured from the Cossacks, with the wounded Cossacks themselves lying high up on the piles of straw. Often in good weather the boys of George's Square would go on long excursions into the country, frequently staying away from home for several days at a time. On one such occasion they found themselves some twenty miles away from Edinburgh without a single sixpence left among them. Walter said afterward, "We were certainly put to our shifts, but we asked every now and then at a cottage door for a drink of water; and one or two of the good wives, observing our worn-out looks brought out milk in place of water--so with that, and hips and haws, we came in little the worse." His father was not at all pleased with his long absence, and asked how he had managed with so little money. "Pretty much like the ravens," said the boy. "I only wished I had been as good a player on the flute as poor George Primrose in 'The Vicar of Wakefield.' If I had his art, I should like nothing better than to tramp like him from cottage to cottage over the world." "I doubt," said the father, "I greatly doubt, sir, you were born for nae better than a scapegoat." It may be that as a result of these chance expeditions Walter's father finally came to realize that the boy might be made use of in certain legal business that required sending messengers into the Highlands. Soon he was sent with some legal papers to the Maclarens, who lived in that beautiful lake country about Loch Lomond which Scott was later to make famous in "The Lady of the Lake." It was the first time he had been in that country, and the changing panorama unrolled before his eyes like a land of dreams. It happened that Walter was traveling in the company of a sergeant and six men from a Highland regiment stationed in Sterling, and so he journeyed quite like some ancient chieftain, with a front and rear guard, and bearing arms. The sergeant was a thorough Highlander, full of stories of Rob Roy and of his own early adventures, and an excellent companion. The trip was a great success, and fired Walter's desires to see more of a country which even then was only half-civilized.
