London April 19.-(Special.) )-The news which comes from Berlin to the effect that the Kaiser intends to violate all precedents and entertain Col Theodore Roosevelt just as though he was mem- Der of a reigning house, instead of merely a private, though unusually eminent, cit izen, has caused surprise here.
 It is regarded as merely another one Of the Kaiser's freaks and illustrates his contempt of custom and precedent when his own wishes are concerned.
 It is doubtful if there is another com moner in the world today who the Ger man monarch would treat on the basis of personal friendship which it is his inten- tion to accord President Roosevelt. While of course it is recognized that the Kaiser in a measure in honoring his guest in- tends to show the depth of his friendship for the United States is actuated by an- other motive, that is a very strong ad- miration for Roosevelt the man, in whom he recognizes kindred spirit.
 The Kaiser would be willing almost to give his right hand if he could take the trip which MT. Roosevelt has just taken, and he wants to hear the details of that marvellous hunt at first hands.
 The unusual honors accorded MT. Roose- welt in Berlin will have their reflex in London and it is pretty certain that the famous American will also be the per sonal guest of King Edward when here.
 It may also be said that MT. Roose- velt's speeches in Egypt will add to the l,f
 While the British war office is not per- haps making as much fuss about it as is the case with some of the continental powers she is keenly alive to the import ance of the airship as means of war fare and has established an air office at Taddington.
 One of the sights at the air office is a tiny model airshop battling against an ar- tificial gale created by gret fan twice the height of man.
 You step upon platform and gaze in at the miniature airship through a window in the side of a great tube, through which the gale of wind shrieks loudly. Facing the platform are a series of deli cate instruments which register the pres- sure of the wind upon the airship.
 By testing models of all shapes and sizes" Dr. T. W. Stanton, superintendent of the engineering department. explained to me, we have now been able to tell the constructonal experts at the Alder shot aerial factory the precise shape of airship which will glide through the air with a minimum of resistance from ed- dies of wind created by it's passage. A slim long craft. tapering finely to the tail, is the ideal
 Other strange scientific instruments fol aerial research work were then shown in actual operation. They included:
 The whirling table-A wonderful device in a specially built hall, in which a great metal arm, projecting 60 feet from a cen tral platform, revolves at high speed. in order to test the thrust of aerial pro- pellers.
 The wind towers-Two skeleton struc- | lures 70 feet high, at the summit of which | the actual lifting planes of full-sized flying machine may be placed, and the precise pressure of the wind upon them | determined by recording apparatus at the | foot of the tower.
 The water channel-A long tank, sur rounded by scientific recorders, and with stream of water of varying speed pass ing through it. in which the eddies formed by planes of different shapes may be studied and a comparison made be- tween the results obtained in water and in air.
 The aerial engine plant-Here, while the engines of an airship are running at full speed under reliability tests, an artificial wind of 30 miles an hour is directed upon them, and they are tilted at all angles so as to mimic actual flying conditions
 ''In connection with the propeller tests we are anticipating results of the high est importance" said Dr. Stanton. We hope to evolve scientific propeller of our own for use in the airships of the army and navy"
 In another department experts were busy with intricate tests upon bars of white. metal. There were aluminium al- Joys of extraordinary lightness upon the benches. We want to find the strongest and lightest metal for tine cars of air. ships" explained the superintendent "So far an alloy of aluminium and copper has given the best results"
 The London Times has anticipated the action of the American Congress. It an- nounced that Rear Admiral Peary, OH his arrival in London. will be enter | tained by the Royal Societies club.
