32 Extracts from the “Journal of a Survey to explore [J ULY, 
the village of Reital, where I halted to make arrangements for 
my progress through the rugged regions before me, in which I 
found | had no chance of getting any supplies of grain for my 
followers: I was consequently obliged to buy grain, and to send 
it off before me, so as to form little magazines at the places I 
intended to halt at; and as I learned that several of the sangas 
or spar bridges over the river had been destroyed by avalanches 
of snow, I sent a large party of labourers to re-establish them. 
Considering Reital as a point of departure, it will be satisfac- 
tory to know its geographical position. By a series of observa- 
tions with the reflecting circle of Troughton, and also by his 
astronomical circular instrument, I found the latitude to be 
30° 48’ 28” N.; and having been so fortunate as to get two 
observations of immersions of the first satellite of Jupiter, and 
one of the second, I am able to give a good idea of the longitude 
of the place; and the more satisfactorily, as two of the immer- 
sions are compared with those taken at the Madras Observatory 
on the same night, and with which I have been favoured by Mr. 
Goldingham, the astronomer there. 
The telescope used by me. in observing the satellites was a 
Dollond’s 42 inches achromatic refractor, with an aperture of 
two and three-quarter inches, and power of about 75 applied, 
having a tall stand, and rack work for slow motion. The watch 
was a marine chronometer, made by Molineux, of London, and 
went with the greatest steadiness on its rate, as nightly deter- 
mined by the passage over the meridian of fixed stars observed 
with a transit instrument. The time of mean noon when required 
was always found by equal altitudes. 
By a mean of several observations taken at Madras about the 
time of four emersions of the first satellite, which I observed at 
Mr. Grindall’s house near Seharanpur. (Mr. Goldingham finds 
5" 10’ 24” for the longitude of Seharanpir.) A snowy peak 
called Sri Canta is visible both from Reital and Seharanpir, its 
position is determined by means of a series of triangles insti- 
tuted by me for the purpose of taking the distances and heights 
of the snowy peaks. I find the angle at the pole or difference 
of longitude between Seharanpur station and Sri Canta to be 
1° 14’ 47”, the peak being east, and at Reital, the difference of 
longitude of that village, and the peak is found to be 12’ 6”; the 
peak heing east, consequently the difference of longitude of 
Seharanpir and Reital is 1° 2’ 41”. On the whole, I think 
5» 14’ 20:6”, or 78° 35’ 60°7” may be safely taken for the longi- 
tude of Reital, east of Greenwich. 
Reital contains about 35 houses, and is esteemed a considera- 
ble village ; as is usual in the upper mountains where timber is 
plentiful, the houses are Jarge, and two or three stories high. 
‘When a house has three stories, the lowest serves to shelter the 
cattle by night; the second is a sort of granary, and in the 
upper the family dwells; round it there is generally a strong
