700 EXPERIMENT STATION RECORD. 



The contractiug countries shall adopt, if not already in existence, the neces- 

 sary laws and administrative organization for carrying out the inspection of all 

 nurseries, greenhouses, and other establishments offering plants for sale, verify 

 reports of the occurrence of insect and fungus pests, investigate means for their 

 control, and adopt regulations for the packing and shipment of plants. The 

 governments shall, within two years, establish institutes for the scientific in- 

 vestigation of plant pests, provide for the inspection of shipments, and give 

 certificates of freedom from disease or insect i^ests. For the present, grain, 

 seed, onions, potatoes, grapevines, and all plants which enter into "grand 

 culture" will not be included in the inspection, but no country shall admit 

 nursery stock, bulbs, cuttings, grafts, or cut flowers from any other country 

 except as accompanied by certificates signed by competent officials in the export- 

 ing countries. Each country reserves to itself the right to examine plants and 

 their packing, and where pests are found contrary to the certificate of the 

 exporting country, notice will be furnished the exporting country, which shall 

 at once take proper recognition of the condition. The infected plants will be 

 returned to the exporter or burned and evidence of their destruction forwarded. 



Certificates of inspection shall be uniform and be printed in French and also 

 in the language of the countrj- of their origin. The importation of living plants 

 without certificates is permitted by scientific institutions duly authorized by 

 their governments, but all reasonable precaution should be taken against the 

 possible dissemination of any pests. For contiguous countries such exchange of 

 plants should be as near the frontier as possible. 



Upon their adherence to the convention the different countries shall furnish lists 

 of plant pests against which protection is desired, and these shall be noted in 

 exporting certificates. This list shall be limited to those pests that are liable 

 to become epidemic or destructive to crops of various kinds, or which are readily 

 propagated on living plants or parts of plants. 



The International Institute of Agriculture at Rome is recognized as the offi- 

 cial center to which all matters regarding plant pests are to be referred. All 

 questions of controversy of two or more countries are to be referred to a mixed 

 commission of phytopathologists for examination with a view to suggesting 

 means for harmonizing the differences. No coxmtry is to extend to a noncon- 

 tracting country any consideration not given the countries signing the con- 

 vention. 



American Association for the Advancement of Science.— In commemoration of 

 the completion of the Panama Canal, an extensive series of scientific meetings in 

 San Francisco and vicinity is being planned for the first week of August, 1915. 

 The meetings concerned with agricultural science will deal in general with 

 questions of food supply and of agricultural conservation, and of these sessions 

 at least one will be devoted to subjects of nutrition, and one to more general 

 questions of agricultural chemistry. It is expected that a number of national 

 chemical and agricultural societies will convene in conjunction with the meet- 

 ings of the American Association.
