|Quotations for Today|
| ||"Over increasingly large areas of the United States, spring now comes unheralded by the return of the birds, and the early mornings are strangely silent where once they were filled with the beauty of bird song."|
| "Saying that each of two atoms can attain closed electron shells by sharing a pair of electrons is equivalent to saying that husband and wife, by having a total of two dollars in a joint account and each having six dollars in individual bank accounts, have eight dollars apiece!" |
| ||"If my efforts have led to greater success than usual, this is due, I believe, to the fact that during my wanderings in the field of medicine, I have strayed onto paths where the gold was still lying by the wayside. It takes a little luck to be able to distinguish gold from dross, but that is all." |

|In 1919, oil was struck at England's first inland oilwell. Since 1915, the British Government, prompted by the war effort and awareness of the importance in petroleum products had investigated extracting oil on the mainland. The bore was 3070-ft deep when oil was struck in a sandy limestone horizon near the top of a faulted dome in the main carboniferous limestone measures. Oil flowed from the well on 7 Jun that year. Between that date and Dec 1927, 2500 tons of oil was produced. The average production of 6 barrels a day compared favourably with US oil wells of the period. In 1938, the well was deepened to continue operation. Production ceased in 1945, and the well was finally capped in 1952. |
Where in England was this oil strike made?
