a. nyer.al underestimate Of the time requiredfor I'M

nace style in which the heat is conducted or rad-

which the arway is filed invites critical attention,
and suggests the inquiry how far the free rise of the

proftably checked by such means. II the air rises

j. A. Ayres of the same place shows large working |
hodels OF two inventions, both fully deserving far more
pace than spare in running notice. The first
fam gate made in halves, and sef-opening and
closing, BY taking care 30 to drive that the wheels
shall crowd down certain elevated panks in the road
way. the gate will open on approaching, an shut on
having it. This idea is not novel, and has been de-
yelopcd in several other formsone by its side, by Mr.
Enos Woodruff balanced lifting gate, being operated
by substantially similar MEANS and very possibly with
equal success. The other invention Of Mr.. Ayres ia

has to earn its living by drawing full of seeds up

what appears to be elaborate and probably highly
