It is probable, that when the returns 
are complete, there will appear, upon com- 
paring the extent of the country with the 
whole number of inhabitants, about four 
acres to each perfon in all England, but a 
much greater proportion in Wales and 
Scotland. Such a comparifon, however,

A friend of mine, Mr. Farey, the Duke 
of Bedford’s agent at Woburn, has re- 
quefted me to communicate, along with 
my journal, the refults of fome obferva- 
tions, which, during the laft fix months, 
he has mace with fix rain gauges of a 
fimilar confruétion to mine. 
Near to the efflux of every river 
into the fea, aridge of high land, more 
or lefs elevated, begins on each fide, and, 
preceeding on towards the fource of the 
river they at laft join and fuiround it, 
forming thé pariage or feparation of the 
water that falls by rain to fupply that 
river from that which goes to other rivers. 
The fame holds good exactly, though ona 
fmaller fcale, of every brook, beginning 
with its junCtion with the river into which 
gt falls. ; 
This gentleman has it in contemplation 
to compare, by a¢tual experiment, the 
quantity of rain which fails within the 
limits of the ridge of hills which furround 
Woburn, and that forms the fupply of 
water to its brook, with the quantity of 
water which that brook aétually dif- 
charges at a bridge fome miles below Wo- 
burn; for which purpole the exact line of 
the fummit of the ridge, in its whole cir- 
cuit from the bridge (where a water- 
gauge is intended to be placed on the 
brook) is intended to be traced out, and 
an exact furvey made of the land which it 
inclofes, which amounts to about eight or 
ten thoufand acres. 
On the firft of January laft, three rain- 
gauges were placed at different points on 
this ridge of hills, numbered I. III. and V, 
and three others in different places in the 
vaies, within the circuit of thefe hills, 
numbered II. IV. and VI. No. I. is 
placed on the ridge of the White Houfe, 
farm-houfe, the top of the tunnel being 
twenty-four feet from the ground ; No.IIT. 
is placed on the top of the riding-houfe at 
Woburn Abbey, at thirty-eight feet from 
the ground ; No.V. on the fteeple of Bow- 
brickhill Church, fifty-four feet from the 
ground ; No. II. is placed on the ridge of 
Crawley Water-mill (being within about 
a mile from the bridge above-mentioned, 
and is twenty-feven feet high ; Na. IV. is 
placed on the ridge of a houfe, called Wa- 
terman’s Lodge, in the vale below Wo- 
burn ; and No. VI, is placed on an ifland 
in Cowhill-pond, in Woburn Park, about
