The "Midsummer Cushion" had been set aside, but Clare had submitted many of the poems together with hundreds more to Messrs. Whittaker. Largely through the recommendations of Mr. Emmerson, the publishers decided to print a volume from these, picking principally those poems which had already shown themselves respectable by appearing in the annuals. One even written in 1820, "The Autumn Robin," was somehow chosen, to the exclusion of such later poems as "Remembrances" and "The Fallen Elm." With faults like these, the selection was nevertheless a distinctly beautiful book of verse. In March, 1834, Clare definitely received forty pounds for the copyright, and finally in July, 1835, appeared this his last book, "The Rural Muse." Its success was half-hearted, in spite of a magnificent eulogy by Christopher North in _Blackwood's_, and of downright welcome by the _Athenaeum_, the _New Monthly_ and other good judges. There was a slow sale for several months, but for Clare there was little chance of new remuneration. This he could regard calmly, for while the book was in the press he had received from the Literary Fund a present of fifty pounds. Clare's malady slowly increased. The exact history of this decline is almost lost, yet we may well believe that the death of his mother on the 18th of December, 1835, was a day of double blackness for him. The winter over, Patty made a great fight for his reason, and at last persuaded him to go out for walks, which checked the decline. Now he became so passionately fond of being out-of-doors that "he could not be made to stop a single day at home." In one of these roving walks he met his old friend Mrs. Marsh, the wife of the Bishop of Peterborough. A few nights later as her guest he sat in the Peterborough theatre watching the "Merchant of Venice." So vivid was his imagination--for doubtless the strolling players were not in themselves convincing--that he at last began to shout at Shylock and try to attack him on the stage. When Clare returned to Helpston, the change in him terrified his wife. And yet, he rallied and walked the fields, and sitting on the window-seat taught his sons to trim the two yew-trees in his garden into old-fashioned circles and cones. The positive signs of derangement which he had given so far were not after all conclusive. He had seen Mary Joyce pass by, he had spoken to her, occasionally he as a third person had watched and discussed the doings of John Clare and this lost sweetheart. He had surprised one or two people by calling mole-hills mountains. One day, too, at Parson Mossop's house he had suddenly pointed to figures moving up and down. Under these circumstances, a Market Deeping doctor named Skrimshaw certified him mad; and on similar grounds almost any one in the world might be clapped into an asylum.
