"We can't go away without Dawn. Don't you like pictures, Puggy? I love them; do let us see some more. Look at that little girl on horseback over there, who is she I wonder?"
"I know I'd like to be on horseback," muttered Puggy; "this is too slow for me. I want to get out of it."
Dawn came skipping up to them, quite unconscious that Puggy was becoming bored.
"Isn't it nice here?" he said. "The rooms are so big. Have you seen dad's pictures, Tina?"
"Puggy is tired of it, he wants to go."
"All right, we will; and we'll go and have some tea in a shop. I know where to take you. Dad and I always go there."
Christina very reluctantly left the pictures and followed the boys out into the street. It was Dawn's way she knew, to be always changing his programme. But when they left the gallery, which had been lighted throughout with electricity, they found that outside, thick darkness prevailed.
"Is it night?" asked Christina with fright in her tone.
"No, it's a regular pea soup fog; isn't it fun? Come on, you follow me! I know the way."
"Don't go so fast," pleaded Christina; "and, please, don't cross the street. I can't see the horses and carts properly, and I shall be run over."
