RULES FOR SEED CONTROL 121 



B. So far as the analysis and control of forest seeds is concerned the experiments 

 will determine: 



1. Correctness, so far as possible, of genus or species. 



2. The purity. 



3. Absolute weight. 



4. The actual weight in case demand is made. 



5. Germinative figure and germinative per cent. 



6. Water content. 



The experiments must be carried out in conformity with exact technical methods. 

 The experiments with knife without being proved by germination may suffice for the 

 large seeds (cembric pine, oak, beech, etc.), but give only approximate results. The 

 results given by the experimental service are obtained by experimenting with average 

 specimens, that is to say that the advertisements of the analysis executed by the ex- 

 perimental service cannot be utiUzed by the vendor as exact data on the value of a 

 given purchase. 



Artide II. — Control of the sale of forest seeds. 



1. Analysis of control. Contract houses (with the aim of controUing the sale of 

 forest seeds) and experimental service can conclude contracts with seed 

 merchants entitled contracts of control. The list of houses placed under 

 the control of the experimental service can be mailed free to persons who 

 demand it. It may be pubUshed. The conditions of these contracts are 

 as follows: 



A. The house promises to observe the rules in every particular. 



B. The house engages to indicate on the bill the guarantees for the merchan- 



dise sold and delivered to the purchasers under the conditions given in 

 the certificates of control and to furnish, at the expense of the house, an 

 analysis of control. 



C. The purchasers of seed from a controlled house acquire, if purchasing the 



minimum amount stipulated, without further formality and without 

 special authorization, the right to have a free analysis by the experi- 

 mental bureau of the material purchased. 



D. The controlled houses must agree that the analysis made by this bureau 



shall be final for the purposes of fixing the amount of the bill. If the 

 results of the analysis do not correspond with the guarantee given, they 

 promise to make it up to the purchaser. 



E. The houses controlled do not pay any annual charges to the testing bureau 



. . since the expenses are borne by the Maison de Commerce. . . . 



F. The houses which do not guarantee to their purchasers free analysis or 



which do not even give a limited guarantee cannot be admitted as houses 

 controlled by the bureau. 



G. The controlled houses are forbidden to furnish several certificates of free 



analysis for a single sale of the same sort of seed. Each certificate is 

 valuable only for the special sale for which it has been deUvered. 

 H. It is forbidden to insert in the contracts of control any stipulations con- 

 cerning the probable analysis cost. The analysis of this kind must be 

 paid for according to the tariff." ° 

 'Such a system of general seed control is needed in the United States. Uijder 

 present conditions a private purchaser of forest tree seeds has no guarantee of the real
