This is a good deal for Blackrock since JB#4 is the closest of HW#1 about 1/2 mile.
JB#2 was a little over a mile away from HW#1
JB#3 was located approximately one mile west of the John Bowen # 1 & # 2 Wells and one mile north-west of the Howard White # 1 Well
JB#4 is located 1/2 mile South of JB#3
If I read right...
