From a window he dropped his books and his crutches over the wall. Then, by clasping his arms around a broken shaft that blocked the casement, he swung himself out, and scrambled down into an enclosed vault yard. There he kept hidden Mistress Jeanie's milking stool for a seat; and a table-tomb served as well, for the laddie to do his sums upon, as it had for the tearful signing of the Covenant more than two hundred years before. Bobby, as host, greeted Tammy with cordial friskings and waggings, saw him settled to his tasks, and then went briskly about his own interrupted business of searching out marauders. Many a spring dawn the quiet little boy and the swift and silent little dog had the shadowy garden all to themselves, and it was for them the song-thrushes and skylarks gave their choicest concerts. On that mid-April morning, when the rising sun gilded the Castle turrets and flashed back from the many beautiful windows of Heriot's Hospital, Tammy bundled his books under the table-tomb of Mistress Jean Grant, went over to the rear of the Guildhall at the top of the Row, and threw a handful of gravel up to Ailie's window. Because of a grandmither, Ailie, too, dwelt on a low level. Her eager little face, lighted by sleep-dazzled blue eyes, popped out with the surprising suddenness of the manikins in a Punch-and-Judy show. “In juist ane meenit, Tammy,” she whispered, “no' to wauken the grandmither.” It was in so very short a minute that the lassie climbed out onto the classic pediment of a tomb and dropped into the kirkyard that her toilet was uncompleted. Tammy buttoned her washed-out cotton gown at the back, and she sat on a slab to lace her shoes. If the fun of giving Bobby his bath was to be enjoyed to the full there must be no unnecessary delay. This consideration led Tammy to observe: “Ye're no' needin' to comb yer hair, Ailie. It leuks bonny eneugh.” In truth, Ailie was one of those fortunate lassies whose crinkly, gold-brown mop really looked best when in some disorder; and of that advantage the little maid was well aware. “I ken a' that, Tammy. I aye gie it a lick or twa wi' a comb the nicht afore. Ca' the wee doggie.”
