108 FORESTRY IN SPAtN. 



7. A pitchman's bucket. This bucket is similar to those 

 in domestic use ; it serves for the transport of resin to and 

 from the receivers and the deposits. 8. Depots or receptacles 

 for the resin. The depot depends in size on the magnitude 

 of the fabrication, and care must be taken to prevent the 

 absorption of the spirit or oil of turpentine. What gives 

 the best results is to Mne it with Roman cement, and paint 

 this with pirogenado oil ; precautions must also be taken 

 against fire.' 



There follows detailed information regarding the various 

 processes employed in the preparation of spirits of turpentine, 

 resin, pitch, tar, and lamp-black ; and of the various uses 

 to which these, and preparations from them, are applied - 

 with all of which it is considered desireable that the forest 

 engineer should be acquainted, or in regard to which he 

 should have at command the information which at any 

 time may be required in the discharge of his functions.

In a paper on the resin trade of Valladolid, by Serior

 the writer says: ' We do not undertake to describe the 

 process of collecting the rough turpentine from the 

 Maritime Pine, Pin an Pinarte, Sol., arid the elaboration of 

 this in the manufactory. Uur purpose is more limited : it 

 is to give a brief sketch of the resin trade in Valladolid, 

 considered from an economic point ot view ; and in entering 

 upon this we believe that the deductions which may be 

 drawn will prove applicable to a great extent to that 

 industry everywhere throughout the Peninsula. 



' Some eight years ago it was proposed to collect the 

 rough turpentine, or raw resin, from 20,000 pine trees, as 

 a means of obtaining a new product from the public forests ; 

 and with a view to securing good results, attention was 

 directed to what had been accomplished in this way in the 

 district of Segovia. To the cutting of these pines succeeded 

 the establishment of a resin manufactory within the 

 bounds of the aforesaid town ; and in the year 1874, by
