Those dogs both live in one house, and have the same master, who is very fond of them, and has trained them to work together; and, when one is sent on an errand, the other always goes too. They are now standing at the door of the school-room, waiting for their master’s children to come out. Jane and Ellen are very young, and would not know how to go and come, without the company of the dogs. They love Carlo and Shag, and are never afraid when they are with them. You see the teacher standing at the door; he wants to know the errand of the dogs. How earnestly they look up at him, as if telling him what they have come for; and Shag has lifted his foot to step on the door-stone. They start off for school so regularly, every day, that it is quite surprising.
