xv; In the Division of Entomology and Botany forage plants have
ic., been given a large share of attention during the year, the plots
gg- on the new addition to the Experiment Farm affording a better
he opportunity than we have hitherto had of testing the various species
mg _of plants adapted in one way or another to furnish food for stock.
Bd Especial attention has been given to plants of the clover family,

Of isms were secured from Germany last spring, and were given
BS- practical tests in our forage plots. It was demonstrated that it is _
to possible to obtain very luxuriant growths of the nodules by the
