cause of abolition. Indeed, like his brother Joshua Young, D.D.
(ostracised from his church at Burlington, Vermont, for officiating at
John Brown's funeral'), Aaron became too vociferous on the subject
of abolition for his own welfare, even in Maine, and found it advan-
tageous to move to New Brunswick.
  With the outbreak of the civil war, his friend Hannibal Hamlin
secured for him a consulate at Rio Grande do Sul, Brazil, which he
held under Presidents Lincoln, Johnson and Grant. There Aaron
Young found a large field of usefulness suited to his temperament,
spending his time and even money in attending the suffering and needs
of the hosts of refugees from the Southern States, in attempting to in-
duce developinent of the natural resources of the country, in laboring
for the improvement of the river and harbor at that port, and col-
lecting a wealth of material for the Smithsonian Institution.2

  A PIECE of wood obtained from a coal mine in Macon County,
Missouri, has added a new species to the interglacial flora of that
state.
   Preglacial erosion, especially in the territory bordering the Middle
Fork in Macon County, Missouri, cut down in places sufficiently far
to remove even the Bevier bed of coal. Clays, containing pebbles and
overlain by drift varying in thickness up to 100 feet, now occupy the
coal horizons (6). A diagram of shaft No. 24 of the Central Coal and
Coke Company in Macon County is shown in FIG. 1. The strata,
including the Bevier coal seam, have been cut through by preglacial
erosion to a hard limestone below. At a point marked "X" the wood
under consideration was found. This wood covered by Kansan till
and occupying the place where the Bevier seam formerly was, is be-
lieved to be pre-Kansan or Aftonian in age.
