"What on earth can have done this?" cried Tod to Jenkins, when he was able to speak. "Well, Mr. Joseph, I say nothing _could_ have done it but the----" "Don't talk rubbish about the devil, Jenkins. He does not work in quite so practical a way. Open the windows." "I was on by half-past five, sir, not coming here at first, but----" "Where's Monk this morning?" again interrupted Tod, who had turned imperative. "The Squire sent him over to Evesham for the seeds. I heard him go by in the light cart." "Sent him when?" "Yesterday, I suppose; that is, told him to go. Monk came to me last evening and said I must be on early. He started betimes; it was long afore five when I heard the cart go by. I should know the rattle of that there light cart anywhere, Mr. Joe." "Never mind the cart. What has done _this_?" That was the question. What had done it? Some blasting poison must have been set to burn in the greenhouse. Such substances might be common enough, but we knew nothing of them. We examined the place pretty carefully, but not a trace of any proof was discovered. "What's this?" cried out Jenkins, presently. Some earthenware pot-stands were stacked on the ground at the far end of the greenhouse--Mrs. Todhetley always called them saucers--Jenkins had been taking two or three of the top ones off, and came upon one that contained a small portion of some soft, white, damp substance, smelling just like the smell that pervaded the greenhouse--a suffocating smell that choked you. Some sulphuric acid was in the tool-house; Tod fetched the bottle, poured a little on the stuff, and set it alight. Instantly a white smoke arose, and a smell that sent us off. Jenkins, looking at it as if it were alive and going to bite him, carried it at arm's length out to the nearest bed, and heaped mould upon it. "That has done it, Mr. Joseph. But I should like to know what the white stuff is. It's some subtle poison." We took the stack of pot-stands off one by one. Six or eight of them were perfectly clean, as if just wiped out. Jenkins gave his opinion again. "Them clean saucers have all had the stuff burning in 'em this night, and they've done their work well. Somebody, which it must be the villain himself, has been in and cleaned 'em out, overlooking one of 'em. I can be upon my word the stands were all dusty enough last Tuesday, when the greenhouse was emptied for the ball, for I stacked 'em myself one upon another." Tod took up his perch on the edge of the shut-in brick stove, and surveyed the wreck. There was not a bit of green life remaining, not a semblance of it. When he had done looking he stared at me, then at Jenkins; it was his way when puzzled or perplexed. "Have you seen anybody about here this morning, Jenkins?"
