bird could only take one at a time. But why should a bird carry a match in its beak? Certainly it must have been trained to do that for a purpose, and a little consideration made that purpose pretty clear. A noisy, chattering bird would probably betray itself at once. Therefore it must be trained to keep quiet both while going for and coming away with its plunder. What readier or more probably effectual way than, while teaching it to carry without dropping, to teach it also to keep quiet while carrying? The one thing would practically cover the other.
"I thought at once, of course, of a jackdaw or a magpie—these birds' thievish reputations made the guess natural. But the marks on the match were much too wide apart to have been made by the beak of either. I conjectured, therefore, that it must be a raven. So that when we arrived near the coach-house I seized the opportunity of a little chat with your groom on the subject of dogs and pets in general, and ascertained that there was no tame raven in the place. I also, incidentally, by getting a light from the coach-house box of matches, ascertained that the match found was of the sort generally used about the establishment—the large, thick, red-topped English match. But I further found that Mr. Lloyd had a parrot which was a most intelligent pet, and had been trained into comparative quietness—for a parrot. Also, I learnt that more than once the groom had 
"Explaining." met Mr. Lloyd carrying his parrot under his coat—it having, as its owner explained, learnt the trick of opening its cage-door, and escaping.
"I said nothing, of course, to you of all this, because I had as yet nothing but a train of argument and no results. I got to Lloyd's room as soon as possible. My chief object in going there was achieved when I played with the parrot, and induced it to bite a quill tooth-pick.
"When you left me in the smoking-room I compared the quill and the match very carefully, and found that the marks corresponded exactly. After this I felt very little doubt indeed. The fact of Lloyd having met the ladies walking before dark on the day of the first robbery proved nothing, because, since it was clear that the match had not been used to procure a light, the robbery might as easily have taken place in daylight as not—must have so taken place, in fact, if my conjectures were right. That they were right I felt no doubt. There could be no other explanation.
"When Mrs. Heath left her window open and her door shut, anybody climbing upon the open sash of Lloyd's high window could have put the bird upon the sill above. The match placed in the bird's beak for the purpose I have indicated and struck first, in case by accident it should ignite by rubbing against something and startle the bird—this match would, of course, be dropped just where the object to
