ON WELLS IN LIVERPOOL PLAINS. 283 
I cannot begin better than by giving a description of one of the 
most remarkable wells in the district, number 20 on the plan. It 
is at Bando head-station, at an elevation, I should say, of 100 or 
150 feet above the plain. The country is basaltic; and immedi- 
ately behind the well rises a range of mountains from 1,000 to 
1,600 feet higher than the myall slope upon which the well is 
situated. The late manager, Mr. W. T. Keene, has obligingly 
furnished me with the following :—“Size-of the well, 7 feet

are now trickling rills, and convey away from the range, In one 
instance at least, quite treble the quantity of the overflow from 
the well. Whether this remarkable state of things is occasioned 
by the sapping of the timber, or whether it occurs through the 
Operation of natural causes, I am not prepared to state ; but “" 
appears somewhat remarkable that the well should have existed 
for several years and the watercourses retained their no con- 
dition for a period extending over thirty years, only to develop 
into permanent springs and streams when the eucalypt: were

Bearing upon question 9 in the form supplied, although not 
exactly in ee te it, Mr. Keene states :—“I knew of an a 
stance on Colly Blue (Colly Blue is on Coomoo Coomoo Creek, . 
plan) where an old well 65 feet caved in. The water in this we 
was limited and very brackish, and hardly fit for stock. A new 
m Obtained.” This fact ai to me to be valuable, 
would prove that the water below the surface is held in channels 
and may be obtained at very short intervals under widely varying 
conditions. In the well which caved in the water was obtain :
