the balloon of the inflammable air, and having obtained a 

 chaise from Kelvedon, and fixed their aerial vehicle thereon, 

 proceeded to Hackney. 



Mr. Sadler states, that when the carrying pigeons which • 

 be took up with him were emancipated from the bag in 

 which they were confined, they took a circular flight, and 

 immediately returned to the balloon, on which they perched 

 as if unwilling to Itave it. Six of them were, however, 

 at length forced from the car, and they winged their course 

 towards the region from v» hence they had come. The 

 seventh, on which the greatest dependence had been placed 

 for carrying intelligence lo the friends of Mr. Beaufoy, 

 instead of obeying the wishes of his master, flew to the top 

 of the balloon, and there kept its station till the descent, 

 when it flew into a tree, from whence it was driven by a 

 boy sent up for the purpose. It did not reach home till the 

 morning following.
