At the end of the 19th century Dutch butter was losing its reputation. After the introduction of margarine about 1870, some dishonest merchants took the opportunity to sell an adulterated article as pure butter. Although the amount of adulterated butter was a small fraction of total output, it did great harm to the Dutch butter trade abroad.Many farmers were slow in adopting the more scientific methods of dairying practised on large farms in Denmark.The depreciation of the butter became a challenge for the government and for dairy farmers. Butter Control Stations under government supervision were readily founded all over the country and farmers who entered the scheme of supervision were allowed to use a government buttermark, guaranteeing that the butter was pure. A parallel control system was made for cheese production. At the same time, production methods were improved by agricultural education.The Government marks succeeded in greatly enhancing the reputation of the Dutch butter and cheese.About the beginning of the 20th century factories gradually took over the production of dairy products from the farmer.

La manifiesta utilidad que reportan a la Agricultura estos pequeños insectos destruyendo abundantemente las colonias de los perjudiciales afídidos de las plantas, que tan numerosos son en ciertas regiones españolas, y especialmente en la levantina, a causa de la multiplicidad de cultivos, es tema más que suficiente para dedicarle, bajo el aspecto de utilidad inmediata, toda la atención y estudio, ya que, según he podido observar, algunas especies, colocadas en condiciones convenientes para su reproducción artificial en el laboratorio, cosa que pocas dificultades presenta por adaptarse perfectamente a la cautividad, serían utilísimos auxiliares en la lucha natural. Pero exclusivamente desde el punto de vista científico, es tan interesante o más el estudio de estos insectos, puesto que son cerca de 5.000 los ejemplares de Aphidiidae que poseo en mi colección, estando representadas casi todas las especies y géneros europeos conocidos, más los que describo como nuevos para la ciencia, rigurosamente comprobados y estudiados. Agradezco mucho a D. Antonio García Fresca, Catedrático del Instituto de Pamplona, la clasificación de las especies de pulgones que figuran en este trabajo.
