Professor Showky Bakir referred to the usefulness of the 

 pathological method for purposes of identification. 



Professor Kuleschoff then demonstrated how the staff at his 

 station distinguish between winter wheat and spring wheat. 

 He stated that, after a number of experiments, they established 

 the fact that spring wheat in their district is characterised by a 

 hairy growth appearing on the first leaf sprouted, whereas in the 

 case of winter wheat the growth is absent or very much less 

 developed. 



Mr. Dorph-Petersen gave detailed information with regard 

 to the comprehensive work of the Danish State Seed Testing 

 Station in the above connection, and distributed for the informa- 

 tion of the delegates two pamphlets entitled " Danish experiments 

 in Plant Culture and Details about the Trade in Controlled 

 Danish Seed," and " Some Prominent Danish Varieties and 

 Strains of Agricultural Plants." 



He especially emphasised the necessity of havmg a sufficiently 

 large number of plants grown in at least two control fields on 

 which to form a judgment. The plants must be examined very 

 carefully several times during their growth (the cereals 5-6 times 

 during the summer) in order to determine whether or not they 

 are true to variety and free from disease. 



Mr. Dorph-Petersen did not consider the praecipitin method 

 reliable" enough, whereas the Hallquist method, by which the 

 yellow and white-fleshed crucifers can be separated, seemed 

 reliable. 



In summing up the discussion, Mr. Dorph-Petersen proposed 

 the appointment of a committee to consider the matters raised 

 in Dr. Chmelar's paper. The names of the persons whom Mr. 

 Dorph-Petersen suggested should constitute the committee are 

 set out in the report of the Thursday afternoon session. 



The Congress unanimously concurred in Mr. Dorph-Petersen's 

 proposal. 



Professor Kuleschoff then exhibited and explained tables and 

 a graph bearing on the question of seed standards, and asked that 

 international regulations might be framed for dealing with this 

 matter. 



(Two papers submitted by Professor Kuleschoff, viz., " Pro- 

 gramme and Organisation of, and Results obtained by, the 

 Kharkow Seed Testing and Control Station," and " A brief 

 sketch of the Development and present conditions of Seed 

 Control in the Ukraine " and one by Professor Issatchenko, 

 " Seed Testing in Russia," have been published in the Internatioiml 

 Review of the Science and Practice of Agriculture, Rome.) 



Mr. Brown hoped that the present Congress would formulate 

 international rules as to uniformity of tests on which could be 

 devised a form of contract which would involve a standard method 

 of arbitration. The proper person to act as arbitrator should be 

 the head of the Official Seed Testing Station of the country of
