"That is quite enough, Alan," said Cecilia. "That is all, Cecilia," I said; "that is how he got to Blighty." "We will now proceed with the subject in hand," said John after a moment's silence. He produced a small crushed piece of green-stuff from his pocket. "The question before the house is, as we used to say in the Great War, '_Qu'est-ce-que c'est que ceci?_' Any suggestions that it is of the Lemon species will be returned unanswered. For my part I say it is Hairy Bittercress." "And I say it's Hazel Catkin," said Margery. "And what says Hubert the herbalist?" asked John, handing the weed to me. I examined it carefully through the ring of my napkin. "Well," I said, "speaking largely, I should say it is either Mustard or Cress, or both as the case may be." I was howled down and retired. * * * * * We heard lots of the weed during the next few days. Each morning at breakfast it sprouted forth as it were. "And how is the Great Unknown?" I would ask. "The Hairy Bittercress is thriving, we thank you," John would answer. "Hazel Catkin," Margery would throw out. "Catkin yourself," from John, and so on _ad lib_. They kept it carefully in a small pot in the window, and if one looked at it the other watched jealously for foul play. "On Saturday," said John, "the Curate is coming to tea. He is a man of wisdom and a botanist to boot--or do I mean withal? On Saturday the Hairy Bittercress shall be publicly proclaimed by its rightful name." "Which is Hazel Catkin," said Margery. Saturday came and Saturday afternoon, and, about three o'clock, the Curate. I saw him coming and met him at the door. "Good afternoon, Mr. Holmes," I said. "You come to a house of bitterness and strife. Walk right in." "Indeed I trust not," he said. "Come with me," I replied; "I will tell you all about it." And I led him on tip-toe to a quiet spot. "Mr. Holmes," I said, "you know the family well. We have always been a happy loving crowd, have we not?" "Indeed you have," he said politely. "Well," I continued, "a weed has split us asunder. My brother-in-law and my younger sister are on the point of committing mutual murder." I explained the whole situation and drew a harrowing picture of its effect on our family life. "Unless you help us," I said, "this Hazel Catkin or Hairy Bittercress will ruin at least four promising young lives." "But I hardly see how I am to----" began Mr. Holmes. I told him what to do. "But surely," he said, "they will know better than that." "No, they won't," I said. "Neither of them knows anything about it, really. Come, Mr. Holmes, it is for a good cause." "Very well," he said. "Perhaps the end justifies the means. We will see what we can do." "Good man," I said. "Children unborn will bless your name for this day's work." I took him to the dining-room, where Margery and John were sitting. "Here is Mr. Holmes," I said. They both made a dash at him.
