"Is it difficult?" asked William.
"No, it is very easy, and can be accomplished within a month. You have only to ride south till you come to the hills, on the highest of which you will see a Ring of beech-trees. Under the hills lies the little village of Washington, and there you may dwell in comfort through the week. But on each of the four Saturdays of the lunar month you must mount the hill at sunset and keep a vigil among the beeches till sunrise. And you must see that these Saturdays occur on the fourth quarters of the moon—once when she is in her crescent, once at the half, again at the full, and lastly when she is waning."
"And is this all?" said William. "It sounds very simple."
"Not quite all, but the rest is nearly as simple. You have but to observe four rules. First, to tell no living soul of your resolve during the month of initiation. Second, to keep your vigil always between the two great beeches in the middle of the Ring. Third, to issue forth at midnight and immerse your head in the Dewpond which lies on the hilltop to the west, and having done so to return to your watch between the trees. And fourth, to make no utterance on any account whatever from sunset to sunrise."
"Suppose I should sneeze?" inquired the King anxiously.
"There's no supposing about it," said the Ringdove. "Sneezing, seeing that your head will be extremely wet, is practically inevitable. But the rule applies only to such utterance as lies within human control. When the fourth vigil has been successfully accomplished, return to us for a blessing and the gray robe of our Order."
"But how," asked the King, "during my vigils shall I know when midnight is due?"
"In the third quarter after eleven a bird sings. At the beginning of its song go forth from the Ring, and at the ending plunge your head into the Pond. For on these nights the bird sings ceaselessly for fifteen minutes, but stops at the very moment of midnight."
"And is this really all?"
"This is all."
