The two mistresses, thus coerced, issued a fiat. Once a day, and no oftener! All arrangements for the afternoon to be made in the morning séance, the rendezvous to be outside, not inside the house.

After this came on the age of signals; whistlings outside the windows, rattling of the railings, comes through letter-boxes and ventilation grids, even—on occasions of special deafness—pebbles thrown against the panes! A broken window, and a succession of whoops making the air hideous during the progress of an extra special tea party, evoked the displeasure of the mistresses in turns, and a second verdict went forth against signals in all forms, whereupon the Garnetts and Vernons in conclave deplored the hard-heartedness of grown-ups, and set their wits to work to evolve a fresh means of communication.

“S’pose,” said Russell, snoring thoughtfully, “s’pose we had a telegraph!”

“S’pose we had an airship! One’s just as easy as the other. Don’t be a juggins.”

But Russell snored on unperturbed.

“I don’t mean a real telegraph, only a sort—of pretend! There’s our side window, and your back windows. If we could run a line across.”

“A line of what?”

“String. Wire. Anything we like.”

“S’pose we did fix it, what then?”

“Send messages!”
