treating large quantities Of seed, the
following suggestions are offered: Pro-
vide Two large vessc!s-as kettles over
Il ire Or boilers on IL cook StOye-the
first containing WARM water say 10 to
1900. the second containing scaIding
water 49, degrees
The first is for the purpose Of WARM
ing the seed preparatory to dipping it
into the second. Unless this precail-
ton is taken il will be difficult TO keep

be used. with which spread wire net

an iron frame could be made at triiling

be stretched. This would allow the

a minute IS required for this 'prepara-

II the thermometer Indicates that the

add small quantities Of cold water.
This will doubtless be the most simple
method Of keeping the proper tempera-
turc and requires only tie addition Of
two small vessels, one for cold and one
for boiling water. Steam, conducted
into the second vessel through Il pipe
provided with a stop cock answers even
better. both for heating the water and
the temperature from time to

Stir the solution before putting it on

The solution gradually loses its strength
