HYACINTH CULTURE AT HAARLEM 167 



George Voorhelm, in the preface to his treatise on 

 hyacinth culture, encourages men of other nations to 

 cultivate the hyacinth, and to sow seeds, and, in his opinion, 

 it would be better that the Dutch should meet with rivals 

 of other nationalities, for if all produced good flowers, they 

 would be able to supply each other reciprocally. He thinks 

 it a pity no other nation should have attempted to second 

 the Dutch in a work which reveals so wonderfully the many 

 mysteries of nature as that of the culture of the hyacinth. 



Maximilien Henri, Marquis de Saint-Simon, wrote Des 

 Jacmthes, de lew anatomie, reproduction, et culture ; also 

 Histoire de la guerre des Alpes, ou Campagne de 171^% 

 Histoire de la guerre des Bataves et des Romains. 



Saint -Simon, born 1720; died 1799 at Utrecht. This 

 Marquis de Saint-Simon was uncle to Claude Henri, Comte 

 de Saint-Simon, founder of the sect called Saint-Simoniennes. 

 I think the Marquis was nephew of the Due de Saint- 

 Simon, author of the Memoires of Louis XIV.
