This first aeromotive, however, has not yet made its appearance, whether from want of funds or of practicability we do not know, but Monsieur Nadar carried his designs triumphantly into effect with the "monster balloon," which in course of time made its appearance, performed flights, attracted the wonder and admiration, as well as a good deal of the coin, of hundreds of thousands in France and England, even conveyed royalty up into the clouds, broke the bones of its originator, and was exhibited in the great transept (which it nearly filled) of the Crystal Palace at Sydenham. While there, we had the good fortune to behold it with our own eyes! The construction of this balloon merits particular notice; but first, it may be remarked that it is well worthy of being named a giant, seeing that its height was only forty-five feet less than that of the towers of Notre Dame Cathedral, namely 196 feet. That Nadar had cut out for himself an arduous task will be readily believed. Touching on this, he writes thus:-- "I have set myself to work immediately, and with difficulties, sleepless nights, vexations which I have kept to myself alone to this hour, and which some one of the days of this winter, the most urgent part of my task being finished, I shall in part make in confidence to my readers. I have succeeded in establishing my balloon, in founding at the same time this journal--indispensable _moniteur_ to the aerial automotive-- and in laying the basis of that which shall be, perhaps, the greatest financial operation of the age. Those who shall see and appreciate these labours, will please to pardon me, I hope, for having wiped my forehead with a little touch of pride, when at the end of a month--one month!--I have said to myself, `it is done!'" The "Giant" was composed of yellowish white silk, of which there were used 22,000 yards at about 5 shillings 4 pence a yard, so that the cost of the silk alone was 5,866 pounds. This was cut into 118 gores, which were entirely hand-sewed with a double seam, and some idea of the vastness of the work may be gathered from the fact that 200 women were employed during a month in the sewing of the gores. For the sake of greater strength the silk was doubled. In other words, there were _two_ balloons of the same size, one within the other. Directly beneath, and attached to its lower orifice, there was a small balloon called a _compensator_, the object of which was to receive and retain for use the surplus gas. When a balloon rises to the higher regions of the atmosphere, the gas within it expands, so that a large quantity of it is allowed to rush out at the open mouth beneath, or at the safety-valve above. Were this not the case, the balloon would certainly burst. This loss of gas, however, is undesirable, because when the balloon descends the gas contracts, and the loss is then felt to be a great one. By collecting the over-flow of gas in the _compensator_, this disadvantage is obviated.
