table the poodle walked about, waiting till a word was proposed,
whether in a loud voice or in a low voice. Only, one essential
condition was that its master should know the word."

"And, in the absence of its master--" said the novice.

"The dog could have done nothing," replied Mrs. Weldon, "and here is
the reason. The letters spread out on the table, Munito walked about
