130 SPAIN - MISCELIANEOUS 



The work of making these general plans and also that for the map 

 are carried out under the direction of the Geographical and Statistical Instit- 

 ute dependent on the Department of Public Education, the technical staff 

 of which is recruited from among the civil engineers of every kind (Bridges 

 and Embankments, Mining, Mountain, Agricultural), Doctors of Science, 

 Engineers of the Military Engineering Department and of the Artillery, 

 officers of the Staff and of the Xavy. They form a single volimteer corps 

 in the above Institute, called the Geographical Engineering Corps. 



Agronomic Work. 



This work is carried out under the direction of the officers of the Finan- 

 cial Department, by the national corps of agricultural engineers, with 

 the assistance of agricultural experts. Their object is to note the cad- 

 astral characteristics of all holdings taken separately, these characteristics 

 being classified as under : 



Physical 

 Caraeteristics in Detail for the 

 Preliminary Cadastre 



P^conomic 



Situation 

 Boundaries 



Cultivation or other Use 

 Area 

 I^egal Kind of Tenure 



Classification 

 Valuation 



These characteristics are noted and registered under the three headings 

 and in the three periods which in the corresponding table are called periods 

 of geometrical operations (surveying), declarations and valuations, generally 

 corresponding with each of the three groups of characteristics we have 

 given immediately above. 



Period of Survey. — ■ The work of this period begins with the measure- 

 ment, according to plans allowing of the establishment of the pre\dous work, 

 of the area of each of the local polygons into which the municipal district 

 is divided, and which in the cadastre form units of intermediate area be- 

 tween the municipal district and the parcel. Each of these polygons is 

 reproduced as a drawing on a separate sheet, in the scale of i in 25,000 

 or I in 12,500, according to circumstances. Within this perimeter, the 

 official of the cadastre traces polygons showing the hmits of the parcels, 

 after they have been recognised one by one with the assistance of those 

 interested belonging to the locality, represented by a Municipal Committee, 

 to which the law gives the name of Committee of Experts {Junta periciat). 

 In these tracings of parcels and on the leaves corresponding, entry is 

 made, definite^, of the situation, boundaries and mode of cultivation, and 

 provisionally of the area, thus completing the indications of the characteris- 

 tics of a physical nature. Indication is also made provisionally of the 

 classification included among the economic characteristics, and the kind of 

 tenure, a legal characteristic.
