But being, as I am, in command of a big Army Corps on one of the most difficult parts of the Front, it is impossible for me to find any time for writing such a Preface. I can but wish your book the greatest success, and hope that it will be widely read. Yours sincerely, AYLMER HUNTER-WESTON. HEADQUARTERS, VIII CORPS, B.E.F., _February 18, 1918_. THE CLIMATE AT THE DARDANELLES By HENRY E. PEARS [After the evacuation of the Peninsula, the following article, which appeared in the _Westminster Gazette_ early in September 1915, was shown to me. After reading it through, I compared the weather forecasts that the author sets forth, and was interested to find that they agreed very closely with the notes on the weather that I had made in my Diary. The article is therefore republished here, as it may be of interest to the reader.—J. G. G.] The dispatch of August 31st of Reuter’s Special Correspondent with the Mediterranean Forces, of which a summary was published in the _Westminster Gazette_ of the 18th inst., speaks of the weather at the Dardanelles and as to there being two months of fine autumn weather in which to pile up stores, etc. It would be more correct to say three months rather than two. It may be interesting to some of your readers to have a few remarks on the weather in the Marmora. Such remarks are based on the results of observations made by a close observer of nature during a period of over thirty years. The fact that particular interest was taken in weather conditions at such a place arose from a cause other than a meteorological interest in the weather, the object being an endeavour to throw light on the migration of birds. Bird naturalists in general, and especially Frenchmen, have fully recognized that the two stretches of land, namely the shores of the Bosphorus and that of the Dardanelles, being the closest points of junction between Europe and Asia, as also the European coast between these points, are the concentrated passage way or route for the huge migratory flocks of birds proceeding from the western half of Europe into Asia. Three results stand out in respect to this migration. First, the absolute regularity of the autumn migration or passage; secondly, certain conditions of weather at almost fixed dates; thirdly, the result of the weather conditions as affecting the density of the flights, the resting and stopping of various birds at certain places. The subject is a very wide one, and is somewhat foreign to the real purpose of my remarks.
