struck by the sight Of multitudes Of
slender poplar trees growing by the
roadsldes and brooksides. Two or three
times in twenty years the branches OF
these poplars are trimmed, and the
light wood thus obtained is dried and
sold to bakers, whose practical science
has taught them that the quick, intense
heat produced by burning poplar is ex-
cellent for giving thick crust to their
bread
1t is said that the production of arti-
fetal indigo by chemical process has
now advanced so far that 1t threatens
the producers Of natural indigo with
very serious competition. The East
Indian indigo cuItivators are urged to
I call in the aid Of science TO improve
their methods before it is too late. Nat
ural indigo still retains one advantage
over the artificial product in the pres
