In Memoriam Tennyson - Late 1890's

George M Hill Publishing company was started in 1898 and published under that name until 1902. In that time, they published the first edition of The Wonderful Wizard of Oz. They started with reprints however so that's why I believe this likely to be printed in the first half of the publishing company's life... The late 1890's as opposed to after their success with Baum.

The poem In Memoriam A.H.H. (1850) by Alfred, Lord Tennyson, is an elegy for his Cambridge friend Arthur Henry Hallam, who died of cerebral haemorrhage at the age of twenty-two years, in Vienna in 1833. As a sustained exercise in tetrametric lyrical verse, Tennyson's poetical reflections extend beyond the meaning of the death of Hallam, thus, In Memoriam also explores the random cruelty of Nature seen from the conflicting perspectives of materialist science and declining Christian faith in the Victorian era (1837–1901), the poem thus is an elegy, a requiem, and a dirge for a friend, a time, and a place. - wiki
