"Thus, on the certificate of our Phytopathological Service, mention 

 is made of the names of the consignor and of the consignee; then of 

 the nature of the package, the number of boxes or bales, and their marks

 certificates attached to each of the boxes or bales. Only when either 

 of the declarations are present, it is certain that the stock is inspected 

 by our Phytopathological Service and that the nurseries, from which
