| 510In sending specimens of plants for investigation it is
desirable to have th eleaves, flowers, and fruit; and, in the
case of bulbous plants, the bulbs, also. When they are
sent from a distance it is best to prepare the specimens
by drying them under pressure between folds of absorbent
paper, otherwise the parts shrink and break so as to
be hardly recognizable. When the dried plants are sent
they should be protected from breakage in the mail by
being inclosed between pieces of stiff pasteboard. Packages
weighing less than four pounds can be sent by mail
at the rate of one cent per ounce. Write the name of the
sender on the outside. In the letter accompanying the
specimens state where collected, the date, and any other
particulars of the plant, whether reputed poisonous, pestiferous,
medicinal, or useful.

Dear Sir:
The Department is collecting evidence on the
reliability of the rings of growth in determining the ages of trees.
Will you kindly furnish any observations you may have made
on the subject, and also if convenient report any further observations
yo umay make.
If you have any trees, whose age is known, which can be sacrificed
for this purpose, we should be glad to receive transverse sections
of such, about three inches in thickness which may be sent at the
expense of the Department. It is desirable to have stated the height
at which the section is taken. If possible it should be low enough
to include the growth made the first year from seed.
Respectfully,
Norman Colman.
Commissioner. | 510In sending specimens of plants for investigation it is
