and wide-spread consternation, and that not without reason. 

 Spain was not an exception to this panic, but at once the 

 forest engineers in various parts of the country came to 

 the front spontaneously, or at the call of the Government, 

 or the entreaty of their compatriots, and the result showed 

 that they were thoroughly competent to deal with such a 

 case. It would fill a volume to detail what they did in 

 prescribing and advocating preventive protective measures, 

 which were adopted and proved efficient; and what they 

 did to expose the insufficiency or other means which 

 elsewhere had become famous. Details of what was done 

 in both of these departments of operations are embodied 

 in a report, published by Government, by His Excellency 

 Senor D. Mariano de la Paz Graells, Professor of Com- 

 parative Anatomy and Physiology, in the University of 

 Madrid, entitled La Phylloxera vaxtatrix. In it is a large 

 volume with an atlas of illustrative plates. It gives details 

 of the natural history of the insect ; of what had been 

 published in regard to it elsewhere ; and of what had been 

 done to avert the evil in Spain and different parts of 

 Europe. 



Sub-Section 3. Applied Botany. 



As with the provision made for the study of Applied 

 Mineralogy and Applied Zoology, so with the provision 

 made for the study of Applied Botany. It was, as 

 might have been anticipated from the immediate relation 

 of botany to forestry, still more copious. 



One valuable contribution to the provision made for 

 aspirants to the membership of the corps of Forest Engineers, 

 enabling them to make themselves acquainted with the 

 latest discoveries in modern forest science, are various 

 publications by Senor D. Rafael Alvarez Seriex, of some of 

 whose writings mention has been made. Amongst these 

 are Geografia-Botanica ; and Estudios Botanico-Foreatales. Of 

 the latter two series have been published, most of them
