Sequoya, who had occupied a prominent position in the affairs of the Old Settlers and assisted much in the reorganization of the Nation, had become seized with a desire to make linguistic investigations among the remote tribes, very probably with a view of devising a universal Indian alphabet. His mind dwelt also on the old tradition of a lost band of Cherokee living somewhere toward the western mountains. In 1841 and 1842, with a few Cherokee companions and with his provisions and papers loaded in an ox cart, he made several journeys into the West, received everywhere with kindness by even the wildest tribes. Disappointed in his philologic results, he started out in 1843 in quest of the lost Cherokee, who were believed to be somewhere in northern Mexico, but, being now an old man and worn out by hardship, he sank under the effort and died--alone and unattended, it is said--near the village of San Fernando, Mexico, in August of that year. Rumors having come of his helpless condition, a party had been sent out from the Nation to bring him back, but arrived too late to find him alive. A pension of three hundred dollars, previously voted to him by the Nation, was continued to his widow--the only literary pension in the United States. Besides a wife he left two sons and a daughter. [370] Sequoyah district of the Cherokee Nation was named in his honor, and the great trees of California (Sequoia gigantea) also preserve his memory. In 1846 a treaty was concluded at Washington by which the conflicting claims of the Old Settlers and later emigrants were adjusted, reimbursement was promised for sums unjustly deducted from the five-million-dollar payment guaranteed under the treaty of 1835, and a general amnesty was proclaimed for all past offenses within the Nation. [371] Final settlement of the treaty claims has not yet been made, and the matter is still a subject of litigation, including all the treaties and agreements up to the present date. In 1859 the devoted missionary Samuel Worcester, author of numerous translations and first organizer of the Advocate, died at Park Hill mission, in the Cherokee Nation, after thirty-five years spent in the service of the Cherokee, having suffered chains, imprisonment, and exile for their sake.
