propriety, avail myself of the repose of Sunday for advancing my measures. I therefore desired Brunel to ask for the Directors' permission. The next time I saw Brunel, he told me the Directors did not like to give an official permission, but it was remarked that having put one of their own officers under my orders, I had already the power of travelling on whatever day I preferred.
I accordingly availed myself of the day on which, at that time, scarcely a single train or engine would be in motion upon it.
Upon one of these Sundays, which were, in fact, the only really safe days, I had proposed to investigate the effect of considerable additional weight. With this object, I had ordered three waggons laden with thirty tons of iron to be attached to my experimental carriage.
On my arrival at the terminus a few minutes before the time appointed, my aide-de-camp informed me that we were to travel on the north line. As this was an invasion of the usual regulations, I inquired very minutely into the authority on which it rested. Being satisfied on this point, I desired him to order my train out immediately. He returned shortly with the news that the fireman had neglected his duty, but that the engine would be ready in less than a quarter of an hour.
A messenger arrived soon after to inform me that the obstructions had been removed, and that I could now pass upon the south, which was the proper line.
I was looking at the departure of the only Sunday train, and conversing with the officer, who took much pains to assure me that there was no danger on whichever line we might travel; because, he observed, when that train had departed, there can be no engine except our own on either line until five o'clock in the evening.
