of the lid.
I yawned in disgust. It was apparent that I was not cut out for a detective, and I bitterly pondered over the difference between dews in real life and dews in a detective story. After a while I rose, walked over to the chest and opened the lid. The interior was wadded with the red wheat straws, and on this wadding lay two curious glass jars, two or three small vials, several empty bottles labelled chloroform, a collecting jar of cyanide of potassium, and a book. In a farther corner of the chest were some letters bearing English stamps, and also the torn coverings of two parcels; all from England, and all directed to the Red Admiral under his proper name of "Sieur Louis Jean Terrec, St. Gildas, par Moeì?lan, Finisteì€re."
All these traps I carried over to the desk, shut the lid of the chest, and sat down to read the letters. They were written in commercial French, evidently by an Englishman.
Freely translated, the contents of the first letter were as follows:
"LONDON, June 12, 1894.
"Dear Monsieur (sic): Your kind favour of the 19th inst. received and contents noted. The latest work on the Lepidoprera of England is Blowzer's How to Catch British Butterflies, with notes and tables, and an introducrion by Sir Thomas Sniffer. The price of this work (in one volume, calf) is ?￡5 or 125 francs of French money. A post-office order will receive our prompt attention. We beg to remain, "Yours, etc.,
"FRADLEY & TOOMER, "470 Regent Square, London, S. W"
The next letter was even less interesting. It merely stated that the money had been received and the book would be forwarded. The third engaged my attention, and I shall quote it, the translation being a free one:
"DEAR Sir: Your letter of the 1st of July was duly received, and we at once referred it to Mr. Fradley himself. Mr. Fradley being much interested in your question, sent your letter to Professor Schweineri, of the Berlin Entomological Society, whose note Blowzer refers to on page 630, in his How to Catch British Butterflies. We have just received an answer from Professor Schweineri, which we translate into French--(see inclosed slip). Professor Schweineri begs to present to you two jars of cythyl, prepared under his own supervision. We forward the same to you. Trusting that you will find everything satisfactory, we remain, "Yours sincerely, "FRADLEY & TOOMER."
The inclosed slip read as follows:
"Messrs. Fradley & Toomer,
"Gentlemen: Cythaline, a complex hydrocarbon, was first used by Professor Schnoot, of Anrwerp, a year ago. I discovered an analogous formula about the same time and named it cyrhyl. I have used it with great success everywhere. It is as certain as a magnet. I beg to present you three small jars, and would be pleased to have you forward two of them to your correspondent in St. Gildas with my compliments. Blowzer's quotation of me, on page 630 of his glorious work, How to Catch British Butterflies, is correct. "Yours, etc.,
"HEINRICH SCHWEINERI,
PH.D., D.D., D.S, MS."
When I had finished this letter I folded it up and put it into my pocket with the others. Then I opened Blowzer's valuable work, How to Catch British Butterflies, and turned to page 630.
Now, although the Red Admiral could only have acquired the book very recently, and although all the other pages were perfectly clean, this particular page was thumbed black, and heavy pencil marks inclosed a paragraph at the bottom of the page. This is the paragraph:
"Professor Schweineri says: 'Of the two old methods used by collectors for the capture of the swift-winged, high-flying Apatura Iris, or Purple Emperor, the first, which was using a long-handled net, proved successful once in a thousand times; and the second, the placing of bait upon the ground, such as decayed meat, dead cats, rats, etc., was not only disagreeable, even for an enthusiastic collector, but also very uncertain. Once in five hundred times would the splendid butterfly leave the tops of his favourite oak trees to circle about the fetid bait offered. I have found cythyl a perfectly sure bait to draw this beautiful butterfly to the ground, where it can be easily captured. An ounce of cythyl placed in a yellow saucer under an oak tree, will draw to it every Apatura Iris within a radius of twenty miles. So, if any collector who possesses a little cythyl, even though it be in a sealed bottle in his pocket--if such a collector does not find a single Apatura Iris fluttering close about him within an hour, let him be satisfied that the Apatura Iris does not inhabit his country.
When I had finished reading this note I sat for a long while thinking hard. Then I examined the two jars. They were labelled "Cythyl." One was full, the other nearly
