colours, or dendrltical figures, nor do they contain so much 
crystallized matter, as those of the Son; but the jaspers are 
more perfect, and are red, honey colour, and black, some of the 
latter especially admitting of a fine polish. 
After two days labour, with a strong fair wind, I was told 
that I was only four coses nearer Banda, than when I left the 
Yamuna, the whole distance being reckoned ten coses; but, 
leaving my boats and travelling by land, it took me from six in 
the morning to eleven to 'reach the town in a palanquin, during 
which time I must have gone twenty miles. The coses of Ban- 
delkhand, the district of which Banda is the capital, are there- 
fore very long. From Banda to the Diamond Mine is reckon- 
ed twenty-nine coses : but I took eighteen hours to perform the 
journey in a palanquin, with relays of bearers, and making no 
halt that was avoidable. The distance, therefore, must be 
seventy miles, as the roads, when I went, were tolerably good. 
As it rained much on my return, the roads were bad, and I 
took much longer time. I must here observe, that the latest 
maps of India, which I have seen published, even by far the 
hest, that of Mr Arrowsmith, represent this part of the country 
very imperfectly. 
Singhapur is a small town at the northern side of the hill, on 
which is built Ajaygar, or the Invincible Fortress, and is twenty- 
four computed coses from Banda. The country between the 
Yamuna and Singhapur is in general level, with, however, many 
projecting insulated rocky hills. That immediately adjacent to 
Banda consists chiefly of a smaU-grained granite ; some of 
which contains red felspar, white quartz and black mica ; and 
some is composed of white felspar and quartz, with black mica. 
Besides the granite, this hill contains also large masses of quartz 
and felspar, very irregularly intermixed rather than aggregated 
into one solid rock. From the ruggedness of their appearance 
I judge that the other small detached hills are of similar mate- 
rials ; but I had no opportunity of examining them. 
At no great distance to my left, in going to Singhapur from 
Banda, I had a ridge of hills, which is a continuation of that 
which, commencing at Rohitasgar and Sahasran on the banks of 
the Son, passes behind Mirzapur and Allahabad, and which^ 
from the last-mentioned place, takes here a large sweep to tlie
