potatoes from Great Britain. Such consignments are to be in 

 clean bags, sealed by an inspector of the Department of Agri- 

 culture, and must be accompanied by a certificate that they were 

 grown on land free from Wart Disease. 



Denmark. — So far, Wart Disease has not been observed, 

 although many tons of potatoes have been examined. The Phyto- 

 pathological Experiment Station of Denmark issues monthly 

 bulletins on plant diseases and the methods of control, while 

 numerous Agricultural Societies occupy themselves with the pro- 

 duction of the best varieties of cereals, and, above all, of those 

 potatoes which are recognised "as being immune to disease. 

 Fields devoted to such cultures are subject to rigorous control 

 in order to guarantee the absolute immunity of the products, 

 which are sold cheaply to members of the Societies. An Order* 

 of 28th January. 1876, prohibits the importation from America 

 of potatoes and potato waste as well as the containers in which 

 they are packed. By an Order of 19th February, 1914, arrange- 

 ments were made for potatoes destined for the United States of 

 America to be inspected. Arrangements have also been made 

 with the Customs and Railway Authorities for at once reporting 

 to the Inspection Committee the importation of potatoes from 

 abroad. 



Germany. — In Germany, Wart Disease is found in the Rhine 

 District, especially south of Cologne, and also in the Hamburg 

 District and in Hoist ein. Elsewhere, there are scattered cases, 

 but only in the Rhine Provinces are fields attacked. In the 

 greater part of Germany, immune varieties only are allowed to 

 be grown where disease is present. Included in the so-called 

 immune varieties, however, are some known to be susceptible 

 to the disease, the reason being the difficulty experienced in 

 obtaining adequate supplies of true immunes. Occupiers of land 

 are required to produce seedmen's receipts for the varieties 

 grown, and Inspectors visit infected or suspected areas and 

 give helpful advice. Steps are being taken in the Hamburg- 

 District to issue an order making compulsory the notification of 

 the disease and the planting of immune varieties only. No general 

 law applicable to the German Empire as a whole exists in regard 

 to plant diseases in general, though the matter is now under 

 consideration. Measures against certain insects or cryptogamic 

 diseases are embodied in laws and regulations issued by the 

 Central Government or by the Governments of the different 

 States in accordance with the needs of the moment. Experi-
