the Egyptians will last indefinitely
so long as it is bone-dry.
There are great many cases.

! keep wood submerged in water, or
in an absolutely air-dry condition. In
Der which is used is exposed to the
weather, and is subjected to decay
simply because it contains enough
air and enough water for the decom
| posing organisms to get foothold.
| Decay Is most serious where the at
mosphere Is warm and damp, be-
cause these conditions are most ia
vorable for lopment. In the
coal mines o ylvania timber
decays in two be years because
| the temperature rs warm and con-
stant and the air is damp. And in the
south, the warm, humid atmosphere
often causes the timber to rapidly
decompose
Decay may be prevented by two
general methods, by treating the
wood with antiseptics thus poison
| ing the food supply of the organisms
which cause decay and by treating
1t with oils which render it water
proof A combination of these two
methods is most commonly used, as
when wood Is treated with creosote
which fills up the pores In the TIM
Der and keeps out water and is also
a powerful antiseptic.

service at Washington, is given over
entirely to the work of experiments

tical assistance is furnished all who |
