          plant will grow in a certain locality is often of distinct value.

The special labels which are attached to the plants sent out 
give a brief description of their uses. The number on the label is 
the Seed and Plant Introduction (S. P. I.) number and corresponds to 
the number of a published description of the plant. Since reports 
may be requested from Experimenters at any time, or a representative 
of this Office may call to inspect their plantings, it is important 
either that the label be kept with the plants, or that a plot be made of 
the planting in order that the location of the plants may be known at 
all times.

Accompanying this catalogue are complete check lists of all 
seeds and plants ready for distribution at the Introduction Gardens 
during the season 1922-23. Applicants for plants or seeds should fill 
out all blanks on the first sheet accompanying the check lists, place 
a check mark to the left of the S.P.I, number of each plant desired, 
and return the lists promptly to this Office. The final judgment, however, 
as to whether a plant should be sent to a certain region must be 
left to the officials of this Office. Plants will not be sent to a 
region thought to be unsuited to them.

Requests are acted upon in the order of the receipt of the returned 
checked lists, and the plants requested are reserved for the 
Experimenter to be sent to him at the time designated by him if it is 
possible to do so. The shipping season as a rule extends from December 
1st to April 15th.

All seeds and plants imported by this Office are examined upon 
their arrival by the Federal Horticultural Board, and the plants grown 
from these original importations are further inspected before they 
are sent out. Every effort is made to insure the distribution of 
only such plants as are healthy and are free from injurious plant 
diseases or insect pests.
