Including the time spent in journeying to and fro between London and Cwm Elan, Shelley spent some three weeks and three or four days on the Welsh trip, which he made in the hope of staying with the Westbrooks at Aberystwith. Leaving him in Radnorshire readers should return to the spring of the year, in order to take a view of the future poet's relations with his sister, his mother and his Uncle Pilfold, from the date of his expulsion from Oxford to the midsummer of 1811. Mr. Timothy Shelley's withdrawal of the invitation he had given Hogg to visit Field Place, and his subsequent conflict with his son, did not cause the young men to relinquish their hope of becoming brothers-in-law. On the contrary, the new obstacles to the achievement of their purpose only quickened their desire for the realization of the romantic project. Whilst Shelley yearned to call Hogg his brother, the vein of romance, that mingled with the north-countryman's lively humour and cynicism, caused him to be enamoured of the young lady, who was known to him only through her poetical compositions, her letters to her brother, and his report of her personal, mental, and moral endowments. But the brother, who loved her passionately so long as she worshipped him without presuming to oppose him in anything, had not been many days in conflict with his father, before he was disappointed in his sister, discovered faults in her poetry, suspected he had thought too highly of her intellect and courage, saw reason to bewail her mental narrowness, and to fear she was not worthy to be the wife of his incomparable friend. What caused this change of feeling and opinion?
