ARTICLES OF AGREEMENT BETWEEN THE AMERI- 
CAN IRIS SOCIETY AND THE BROOKLYN 
BOTANIC GARDEN 
The American Iris Society, hereinafter called the Society, and 
The Brooklyn Botanic Garden, hereinafter called the Garden, 
hereby agree to cooperate for the purpose of establishing a col- 
lection of Japanese irises and for the study of their cultivation, 
nomenclature, classification, and comparative merit, and for such 
other matters as may be hereafter agreed upon. 
This agreement is to extend over a period of five years, extend- 
ing from 1920 to 1924 inclusive, and may be terminated upon 
one year's notice by either party or extended by mutual 
agreement. 
The Garden agrees as follows: 
1. To provide land within its own grounds, labor of planting, 
and proper care and maintenance. 
2. That all records relating to the subjects of study, excluding 
notes of a strictly preliminary nature, shall be kept in duplicate 
and one copy supplied to the Society for use and preservation. 
3. That any standards (of classification, methods of record- 
ing, etc.) which may be accepted by the Society shall be used 
when pertinent or applicable, and that nothing tending to establish 
a standard in respect to Iris shall be published without the previ- 
ous approval and consent of the Society or its Board of Directors. 
4. That data secured from this collection shall be open to the 
use of the Society and that any Bulletins thereon published by the 
Garden shall be furnished to the Society in number equal to 
twice the amount of the then membership. 
5. That stock of irises furnished by the Society or stock result- 
ing from its increase shall not be disposed of by sale or exchange 
except with the approval of the Board of Directors of the Society. 
Lhe Society agrees as follows: 
1. To furnish without charge the necessary stock that can be 
secured through the contributions of its members or from inter- 
ested growers. Three plants constitute a test; one or two may 
be provided. 
2. To cooperate fully in the collecting of data.
