This account has shown that quarry ownership was a risky business; yet another disaster befell Robert in 1900:
There was an unusual collapse here in the quarry of R. L. Jones last week. It is not an area known for such an event; but they had been vigorously attacking it to remove the slate. The quarrymen have been thrown out of work for a season. This is the Big Quarry. It was here that the late Rowland Parry, Esq., made his fortune, and he sold it to Isaac Parker. but because he was ignorant about quarries and was not prepared to be guided by anyone, he left the old quarry filled with rubble and water, and in that state it remained for 15 to 20 years, but R L Jones took it on, cut a tunnel into it, drained the water out, cleared all the rubble from it, and it began to pay excellent dividends. But on Tuesday, the 11th of August, it collapsed completely without warning, falling from the top and amassing from the bottom up. It is not known yet how much slate is in the fall as it collapsed from underneath, so from above one can see only the rubble accumulated by man over the years. The old quarry is no longer workable. This was the original quarry in West Bangor; it was the first to be worked, if not the first ever to be opened in the area. [YD 27 Dec 1900]
On the next page, a gentleman mentions that Robert, Isabella and one of their daughters visitied UK. The only clear evidence I have found of a voyage back to UK was that Mrs R L Jones and child Idris, aged 10, (clearly her son, though he was listed as female) embarked at Philadelphia aboard the Waesland arriving at Liverpool on 9 May, 1901.
Miss Ellenor Williams visited America in 1905 and reported meeting Isabella and Robert:
There are some old Welsh settlers in the areas. Mrs. R. L. Jones went with me in her vehicle to see the old and infirm, and to maintain a service at home. Mrs. Jones is a member of the family of the late Sir Hugh Owen of Fallwyd. He did much for Wales in his lifetime.” [The London Welshman, 17 June 1905 p.11]The genealogical information requires further investigation but this report shows that Isabella continued to be involved with helping her neighbours. Incidentally, Miss Williams noted that the people of West Bangor and Delta had conserved their religious convictions and that the two Welsh denominations combined in Sunday worship but she also mentioned that there had been some religious discord at the beginning of that year.
