Considerable attention is paid to education, which in the primary grades is free but not compulsory. The percentage of illiteracy is about 70. Bogotá has a National University with Schools of Medicine, Law, Political Science, Engineering, and Natural Science. Connected with it is the National Library, an Astronomical Observatory, a School of Fine Arts, and an Academy of Music. A free institute of learning is the Universidad Republicana; there is also a School of Arts and Trades, giving both general and technical instruction, as in printing, carpentry, etc.; a _colegio_ or school for secondary instruction, La Salle Institute, the largest in Colombia, which prepares for the University; and a Homœopathic Institute, from which at least one woman has been graduated. There are universities also at Cartagena, Popayán, Pasto, and Medellín; in the last named city, a School of Mines, which is a part of the National University. Elementary instruction is the most zealously promoted in Antioquia, Caldas, Boyacá, and Cauca; in the other Departments the school attendance is poor. In Colombia, Spanish is spoken with greater purity than in most of the other Republics. Institutions giving instruction in agriculture, in arts and trades, and in general science are greatly needed, as also the teaching of sanitation and hygiene. PRESS, RELIGION, ETC. =Press.= The Press is free, and bold in discussion. =Religion.= The Constitution recognizes the Roman Catholic Religion as that of the country but permits other forms of worship. =Telegraph.= The 700 telegraph offices are connected by 13,750 miles of line. Colombia has cable connection at Buenaventura, San Andrés, and Barranquilla; wireless stations at Santa Marta, Puerto Colombia, and Cartagena. An international wireless station is expected at Bogotá in 1921. Other stations will be at Barranquilla, Arauca, Cúcuta, Cali, Medellín. There are 13,000 miles of telephone wire.[3] [3] For postal regulations to all the countries see Appendix. =Money.= The money of Colombia approximates our own: that is, a gold peso is worth 97.3 cents. Five pesos equal an English sovereign. A condor is 10 pesos; a medio condor, 5 pesos, an English pound. Silver coins are 50, 40, and 10 centavos or cents; nickel coins are 1, 2, and 5 cents. The =Metric System= of weights and measures is legal and official as in all the other Republics, although to some extent in domestic business the old Spanish measures are used; as libra, 1.10 pound, arroba, 25 libras, quintal, 100 libras, cargo, 250 libras. The vara, 80 centimeters, and the fanega, about a bushel are other measures. The litre is of course the standard of liquid measure. CHAPTER III COLOMBIA: PHYSICAL CHARACTERISTICS
