AERIAL NAvIGATIoN.-It is hardly necess sary to say that the introduction of locnlo- tive machine which would transport a large number of persons through the air in any di-- rection required, at the rate:Ao 30 miles an hour, would be astartling novelty insour trav- zeling arrangements. Let us glance at the ad- vantages it would offer. Comparing it first with aquatic locomotioD, it would be far quicker than any boat hitherto made, vastly less expensive in first outlay and cost of work ing, would require no harbors, would produce n6 sea sickness aRd would escape the great est dangers inherent in water navigation
 Viewing it, secondly, as means of land transport, it would be quicker than common road travelling, and would compare fairly with the ordinary speed on railways, while it would entirely dispense with the enormous and costly provisions requisite for both these modes of getting over tn. ground, and be free from the multitude of liabilities to accident attending them, But it may naturally be ob- jected that such mode of locomoiion would have peculiar dangers of it's own. No doubt balloons have hitherto been very subiectto accidents, andthe bare idea uf anything going wrong at height oi thousands of feet above the earth, has in it something very appalling. But much of this impression will vanish be- fore common sense reasoning 1t must al- ways be borne in mind that, for the purposes of loeomotion there would be- DO reas6l for ascending high intosthe air; itwoad ohE be necessary to keep at a snfficiehtI altitude to clear terrsstrial impedmentsr andlhisswould not of4y do away wftfA much Of the terror of the idea. but would greatly increase the prob- ability of safe escape from accidents of whatever kind. Let us see in what direction danger might, in extreme cases, lie. The loss Pof gas, by rupture of the envelope or other-1 wise, is remote possibility, but the exper- fence of many actual cases has proved that the resistance of the air 10 the large surface ex- posed has sufficed to prevent any rapidfall; special smeasures might-be easily provided, and at low elevations overs land 10 serious1 catastrophe needbes feared on this ground In crossing over Water precautions would sill be fpossible, and the case would notb so hope less as in many marine casualties. The dan ger of fire, if properly guarded against need
 not be greater than in ship at sea Indeed, if we believe M. Giffard, who has tried the experiment, the idea of such danger is quite an illusion. The accidents that arise to ordi- nary balloons almost always occnr in the de- scent, which, if the wind is high requires
 great care and skiIful management. In this case the .propelling power would be most es- pecially useful the aerepapt could choose hls place. Of landipg with precision. aud. by turn
 ing his beadto thewind,N he ctud avoid the dragging which is so dangerous, and which
 has so often brought fatal termination to balloon voyages The worst conjuncture con- ceivable would be break down of the pro
 polling machinery. at "a time when it was
 wanted to aid the descent in gale. But the risk of such a break down could be made very slight by ordinary mechanical precautions.
 On the whole there can be no good reason to believe that the dangers would be more for kmidable with this than With other kinds of i0comotion. and when we remember the fright
 ful casualties that SO frequently now occur in l land, river and Sea traffic and consider how
 many of thei: causesE would be- absent in the r free paths of the afr, we may probably even
 venture to assert that balloons would be the safest as well as the plessantest mode of trav- kellng. As saFset-of against all this however, there is one great objection to aerial loccomo- tiOn. namely, the uncertainty it mnst always be liable to in consequence of the effect of the wind We must not ignore this j. on the con |etrary, we will endeavor to estimate it's exact value. We will assume that we can steam through the air in any direction at the rate of 30 miles an hour; Bnt this will oaly count for useful locomotion in dead calm; if there is any wind, by carrying the balloon along with it it will clearly influence both the ef- fective direction and the effective speed.
