time certain influential Teuton aeronautical experts who had

previously ridiculed Zeppelin's idea had made a perfect

volte…face。  They became staunch admirers of the system; while

other meteorological savants participated in the trials for the

express purpose of ascertaining just what the ship could do。  As

a result of elaborate trigonometrical calculations it was

ascertained that the airship attained an independent speed

of 30 feet per second; which exceeded anything previously

achieved。  The craft proved to be perfectly manageable in the

air; and answered her helm; thus complying with the terms of

dirigibility。  The creator was flushed with his triumph; but at

the same time was doomed to experience misfortune。  In its

descent the airship came to 〃earth〃 with such a shock that it was

extensively damaged。  The cost of repairing the vessel was so

heavy that the company declined to shoulder the liability; and as

the Count was unable to defray the expense the wreck was

abandoned。



Although a certain meed of success had been achieved the outlook

seemed very black for the inventor。  No one had any faith in his

idea。  He made imploring appeals for further money; embarked upon

lecturing campaigns; wrote aviation articles for the Press; and

canvassed possible supporters in the effort to raise funds for

his next enterprise。  Two years passed; but the fruits of the

propaganda were meagre。  It was at this juncture; when everything

appeared to be impossible; that Count Zeppelin discovered his

greatest friend。  The German Emperor; with an eye ever fixed upon

new developments; had followed Zeppelin's uphill struggle; and at

last; in 1902; came to his aid by writing a letter which ran:



〃Since your varied flights have been reported to me it is a great

pleasure to me to express my acknowledgment of your patience and

your labours; and the endurance with which you have pressed on

through manifold hindrances till success was near。  The

advantages of your system have given your ship the greatest

attainable speed and dirigibility; and the important results you

have obtained have produced an epoch…making step forward in the

construction of airships and leave laid down a valuable basis for

future experiments。〃



This Imperial appreciation of what had been accomplished proved

to be the turning point in the inventor's fortunes。  It

stimulated financial support; and the second airship was taken in

hand。  But misfortune still pursued him。  Accidents were of

almost daily occurrence。  Defects were revealed here and

weaknesses somewhere else。  So soon as one trouble was overcome

another made itself manifest。  The result was that the whole of

the money collected by his hard work was expended before the ship

could take to the air。  A further crash and blasting of cherished

hopes appeared imminent; but at this moment another Royal

personage came to the inventor's aid。



The King of Wurtemberg took a personal interest in his subject's

uphill struggle; and the Wurtemberg Government granted him the

proceeds of a lottery。  With this money; and with what he

succeeded in raising by hook and by crook; and by mortgaging

his remaining property; a round L20;000 was obtained。  With this

capital a third ship was taken in hand; and in 1905 it was

launched。  It was a distinct improvement upon its predecessors。 

The airship was 414 feet in length by 38 feet in diameter; was

equipped with 17 gas balloons having an aggregate capacity of

367;000 cubic feet of hydrogen; was equipped with two 85

horse…power motors driving four propellers; and displaced 9 tons。 

All the imperfections incidental to the previous craft had been

eliminated; while the ship followed improved lines in its

mechanical and structural details。



The trials with this vessel commenced on November 30th; 1905; but

ill…luck had not been eluded。  The airship was moored upon a raft

which was to be towed out into the lake to enable the dirigible

to ascend。  But something went wrong with the arrangements。  A

strong wind caught the ungainly airship; she dipped her nose into

the water; and as the motor was set going she was driven deeper

into the lake; the vessel only being saved by hurried deflation。



Six weeks were occupied in repairs; but another ascent was made

on January 17th; 1906。  The trials were fairly satisfactory; but

inconclusive。  One of the motors went wrong; and the longitudinal

stability was found to be indifferent。  The vessel was brought

down; and was to be anchored; but the Fates ruled otherwise。  A

strong wind caught her during the night and she was speedily

reduced to indistinguishable scrap。



Despite catastrophe the inventor wrestled gamely with his

project。  The lessons taught by one disaster were taken to heart;

and arrangements to prevent the recurrence thereof incorporated

in the succeeding craft。  Unfortunately; however; as soon as

one defect was remedied another asserted itself。  It was this

persistent revelation of the unexpected which caused another

period of indifference towards his invention。  Probably nothing

more would have been heard of the Zeppelin after this last

accident had it not been for the intervention of the Prussian

Government at the direct instigation of the Kaiser; who had now

taken Count Zeppelin under his wing。  A State lottery was

inaugurated; the proceeds of which were handed over to the

indefatigable inventor; together with an assurance that if he

could keep aloft 24 hours without coming to earth in the

meantime; and could cover 450 miles within this period; the

Government would repay the whole of the money he had lavished

upon his idea; and liquidate all the debts he had incurred

in connection therewith。



Another craft was built; larger than its predecessors; and

equipped with two motors developing 170 horse…power。  Upon

completion it was submitted to several preliminary flights; which

were so eminently successful that the inventor decided to make a

trial trip under conditions closely analogous to those imposed

for the Government test。  On June 20th; 1908; at 8:26 a。m。  the

craft ascended and remained aloft for 12 hours; during which time

it made an encouraging circular tour。  Flushed with this success;

the Count considered that the official award was within reach;

and that all his previous disasters and misfortunes were on the

eve of redemption。



The crucial test was essayed on August 5th; 1908。  Accompanied by

twelve observers the vessel ascended and travelled without

incident for eight hours。  Then a slight mishap demanded

attention; but was speedily repaired; and was ignored officially

as being too trivial to influence the main issue。  Victory

appeared within measurable distance: the arduous toil of many

patient years was about to be rewarded。  The airship was within

sight of home when it had to descend owing to the development of

another motor fault。  But as it approached the ground; Nature; as

if infuri
