and everything in connection therewith, could keep pace with tha 

 increasing demand; that warehouse-room and machinery could be 

 improved upon and gradually enlarged. Secondly, that the demands 

 put in regard to the qualities of the various seeds were not so 

 stringent then as they are nowadays, but extended themselves in 

 time and in accordance with the deeper and sounder knowledge 

 that was being acquired by practice. 



Needless also to say, that Mr. Arnold Burgers found 

 great assistance since some 25 to 30 years in the co-operation of 

 his son, Mr. Bernard Burgers and of the author of this 

 book, Mr. Joseph Theodore Barenbrug, two other 

 junior members of the firm of Barenbrug, Burgers & Co., 

 who, whilst the originator planned and traced out the course to 

 be followed, were, each in his way, the men to carry out those 

 plans and improve on them, wherever practice indicated improve- 

 ments to be possible, or showed, that in one way or other for 

 practical reasons, the original way adopted was less adviseable to 

 be followed, had to be deviated from, and that it was necessary 

 to march in an other direction. 



The various factors, however, once having been set in working- 

 order, and the individuals having been put in the right places, the 

 trade made regular and even rapid progress. And it may be stated 

 without any exaggeration in the least, that now the Natural Grass- 

 seed trade in Holland, with Arnhem as its centre, is at-present 

 one of the most important in the world. 



And that this export-trade is an exceedingly lively-one, will be 

 clear to anybody, if we mention here as a fact, that it is practi- 

 cally expanded all over the civilized world now, Europe, as 

 being the cradle taking, of course, the foremost place. 



It was in Great Britain since the middle of last century, 

 that both the trade and farmers, first of all, got gradually fully 

 alive to the importance of the Natural Grasses for the purpose 

 of laying down permanent pasture. And it may be said without 

 any exaggeration, that all over the British Islands, the 

 Natural Grasses are now being used for permanent pasture-land, 

 and that in the number of importing countries it stands foremost. 



Next to this country it was France, Belgium, Germany 

 (we don't speak here of the exporting-ftrms, but of the seed-dealers 

 and farmers for the consumption at home) Austria, Denmark, 

 etc., which got gradually alive to the importance and the indis- 

 pensibleness of them.
