proposition_n be_v plain_a since_o the_o sun_n beam_n must_v not_o only_o penetrate_v deep_a in_o the_o summer_n than_o the_o winter_n but_o also_o because_o the_o solidity_n or_o porousness_n of_o several_a part_n of_o the_o earth_n may_v dispose_v the_o soil_n to_o heat_n or_o coldness_n but_o to_o proceed_v it_o be_v remarkable_a that_o the_o uppermost_a region_n be_v much_o more_o

of_o the_o sun_n beam_n be_v much_o weaken_a by_o those_o side_n be_v plain_a since_o by_o such_o like_a mean_n the_o heat_n of_o the_o sun_n may_v be_v so_o break_v as_o to_o preserve_v ice_n from_o thaw_v all_o summer_n and_o not_o only_o so_o but_o if_o those_o subterraneal_a cavity_n be_v sufficient_o guard_v with_o a_o cover_n of_o brick_n well_o clay_v over_o and_o be_v by_o that_o mean_n

so_o that_o though_o the_o coldness_n of_o subterraneal_a cavity_n may_v conduce_v yet_o it_o be_v not_o altogether_o requisite_a to_o preserve_v ice_n from_o a_o thaw_v but_o the_o subterraneal_a region_n be_v not_o only_o preserve_v from_o excessive_a heat_n by_o prevent_v the_o intercourse_n of_o the_o internal_a and_o the_o external_n air_n but_o may_v be_v considerable_o lessen_v in_o such_o cavity_n as_o be_v considerable_o expose_v to_o the_o open_a air_n as_o i_o myself_o have_v observe_v in_o a_o iron_n mine_v not_o above_o twelve_o foot_n deep_a as_o as_o it_o be_v to_o be_v observe_v that_o this_o cold_a region_n of_o the_o air_n be_v not_o apt_a to_o be_v influence_v by_o external_a heat_n in_o the_o summer_n so_o neither_o be_v the_o hot_a region_n subject_a to_o be_v
