Professor Pepper's Rain Hablnk

' Experiments'

On Saturday lut the Brisbane raceoonne wai attended in the afternoon seme 600 or 700 persons (says the tfcw<»r),who went then in order to witness thb series of scientific experi

ments, and especially the novel feat of " tappihg' the iclouda" Djftaeana of a giganUo kite, and concOTrionpromtiea .to bo attempted by fro feosor Pepper. '

The main feature of the affair was a oamplete' failure, and the experiment whichtheprofessor expressed hja desire to Attempt jft/t Dot tried, although the «tinosph&ric 6oti J i tjtms Win most favourable, heavy rain-clouds hanging loir and a steady breeze blowing nearly all the time.

On arming at tha ground preparation! of different kinds were visible, an anemometer, fox indicating the velocity of the win.t was at writ, and an 'electrical machine was' in Muinws tor use. There were also fixed on post* ten small swivel gnns of an antiquated pattara. By noon a commencement was made by .(bp explosion of a small charge of dynamite by eleotrioity, and two or three large rockets wert fired. The swivel gnns were fired separately at intervals during the afternoon, no attempt: bring qude to produce a oonoussion by -firing them simul

taneously by means of alootrioity. Shortly ; after 2 oclook the Bret attemptaVkiteflying] was piade.

It weald scarcely be believed thit It oould have been thought possible id make each; ah affair rise from the ground in anything short of a hurri cane i every effort, to [to' so resulted utter failure., fibortlyaftorwards a ftiwmOW rockets were discharged, and a large charge of dyna mite waa exploded. Two of the rockets were very carelessly lpindjed,,, (One wept otreMtfc fence bf the course, and exploded en the ground,' and another took an emtio flight in an opposite direction, foTtqaatelyeot jjf&e way of tha crowd, or a serious accident eoight have oc curred. Jjfhe people became clamorous, for'tbe "great experiment" of tha day, an efent that had been anxionsly expsoted, "tha raising of the large kite that was to have tapped tha clouds. This ntoved an even mots conuriouoas

failure than Uhe preceding attempt Nothing wonld induoe the unwieldy affair to leave the ground, and the efforts to raise It were greeted with ahouta of laughter. At last the leering crowd took poaseaafon of the whole affair and tried their .hands, but with no greater eneoees. In bet, the good hnmour of the (feotatoVs waa remarkable; in many places a nmilar public disappointment weald have raised' angty feel ings. Not a little of their good humour was due to the'laudable exertions of a lady profes sor of the art of equiponderant disturbance, with the assistance of a^highly-traSned donkey, whioh created infinite fan by the'skilful manner in whioh it flung off all who attempted to Tide on it This ana the exoellent playing of the Artillery band served to divert the crowd, and induced them to regard in ia merciful spirit the pseudo-seiehtiflo flattxt t&ejr had come, to w/t ness.

Professor Pepper 'writes to the dourier in explanation of me above as follows :

The experiments of Saturday, although, ajl suocessfplexcept so faraa the stool kite was concerned, have developed certain1 truths which cannot bo . gathered from ahybooks, because vary little «r nothing Mayet been worked oht in TOlationto these Va^tivo 'flying maohines.: My object in having ft steel fnuqe for tbp laixe kite was to secure the utmost strength of material, and the. steelwork of Messrs. firookee and Foster did its wqrk wall,, bending but not breaking. The bamboo work gave way at the head of the kite, where it was made to flap or turn over to save space in packing. But the strength of the msterial (steel) ia aooompanied withtoo mnoh weight, and although I had the kite reduced 14x74 feet to make it mora manageable, the weight of the steel waa fatal to the rising power of the kite, and therefore I shall return to the oldfaahioned light kites, and will have two made 12ft. high ef bainboo cane and thick line (as used in the theatres), with thin glazed calico. Directly they sire made I shall resume the experiments, beoauae I am con fident that my scientific principles are right; but the manipulation of the kite is a novelty with me, ana, like " Plalissy the Potter," I shall go on as an earnest student until I suo

oeed.

It waa curious to note, after Mr. Harris's guns had been discharged, the rockets sent up, and dynamitea mines exploded by the eleotrio spark, titat nun fell about 2 p.m.
