On the 12th of March at the same place, the flow was 
57°48 cubic feet per minute, and on the 16th April it 
ceased to flow. The largest quantity flowing out of the 
Bourne culvert at Croydon was on the 27th March, 
when it was 69°45 cubic feet per minute. 
The flow of this Bourne did not extend down the 
valley more than about half a mile below Kenley rail- 
way station where it disappeared into the ground. 
After this year the Author did not give so much 
attention to flows of the Bourne except the prediction 
of the times of their appearance. 
In 1889 there was a small flow of the Bourne in 
April of which no particular observations were made. 
In 1891 and 1892 a moderate flow of the Bourne 
occurred. The Bourne broke out on the 10th December, 
1891, and it was reported by the Borough Engineer 
of Croydon that on the 23rd January, 1892, the flow on 
the surface had reached to within a few yards of the 
east side of the main line of railway at Purley. Shortly 
afterwards it decreased, and the flow on the surface had 
receded to Foxley Hatch House, a distance of about 
350 yards. 
In 1893 another Bourne broke out in the Caterham 
Valley. This was only a flow of a moderate extent. 
On the 8th April it was flowing at the rate of 180 cubic 
feet per minute below the ‘Rose and Crown.” It 
only flowed down the Valley as far as Little Roke Farm, 
and there disappeared into the ground. 
In 1895 another Bourne made its appearance in the 
Bourne Channel below the “ Rose and Crown,” but it 
only just appeared on the surface and lay in the bottom 
of the channel, and then went back without actually 
flowing. 
In 1897 a further Bourne broke out below the “ Rose
