We heard last night of a crevasse on Ascension plantation. Went there, starting at 8:45 AM and reaching the scene about 10:30 AM. Gap 39 feet. It occurred yesterday about noon. A double cribbing was at one build around it on river side in a long horse shoe shape and filled in with earth bags. It was pretty effectually closed by 11:00 AM today. But an inner cribbing will be installed, just in case. Returned home around 4:00 PM so as to relieve Mr. Beirne's anxiety.
