 Engineers, and member of various scientific societies at 

 home and abroad. It treats of the organs, the physiology, 

 the influence of atmospheric agencies, and the longevity 

 and death of trees; it enters then on the consideration of 

 all that relates to the culture of trees, and to the greatest 

 possible extension of woodlands, with a view to aiding in 

 which there is given a monograph on the culture required 

 by each species ; with notices of what is required in this 

 in gardens, in pasture lands, in the open country, in parks, 

 &c. ; and the work concludes with observations on the 

 utilisation and profitable exploitation of woodlands ; and a 

 recapitulation of the Spanish forestal legislation, which 

 might affect or interest proprietors. The author states 

 that he has throughout these lectures made use of the 

 doctrines advanced in the work on the same subject by 

 M. Du Breuil. 



In 1874- was published in Tarragona, under the leading 

 title of Estudios Forestales two volumes by D. H. Ruis 

 Amado, Forest Engineer, treating of the forests in their 

 relation to the necessities of the village population. The 

 author held the rank of Forest Engineer-in-Chief of the 

 first class In this are discussed numerous matters pertain- 

 ing to forestry. The work was held in high estimation, as 

 was also the author, to whom was awarded a gold medal 

 for its publication. 



Interested as the authors of these several works were as 

 professional men, in the professional work to which they 

 were more immediately called, they saw, as enlightened 

 patriots, that by them, if not also by all who engaged 

 in a similar calling, the importance of replenishing divested 

 forests, and creating an extension of the woodlands of the 

 country, was being realised, as it had not yet been realised, 

 by the mass of their countrymen.
