THE CUBA REVIEW 



mixture is passed from one cell to another, the valuable metal, or copper, being- carried in 

 suspension. The ore now enters the concentrators after the foregoing washing and mixing 

 processes, and that portion of the ore bearing fluid is passed over the concentrating tables and 

 collected for shipment. The fluid which has been carr>-ing the foreg)ine- processes, and which 

 sti'l retains much value is finally delivered to the precipitation beds, where it flows over 

 heaps of scrap steel, iron, zinc, etc., and practically all of the remaining ccpper in solution is 

 precipitated on the scrap ir )n and is cleaned up at regular intervals, yielding about 80*; f pure 

 copper metal. This copper precipitates and the concentrates are bagged and shipped for final 

 treatment at the smelters in the United States. 



HAVANA PRIVATE WATCHMEN. 



The watchman of yore, with lighted lantern 

 in one hand and uplifted lance in the other, 

 readyfor defense, has passed away. He hailed 

 the passing hour i:i stentorian tones, from ten 

 o'clock to break of day, and hourly announced 

 the time and weather. He sometimes slept at 

 his post or went on his beat, with eyes half 

 closed and yawned with weariness. Generally 

 these guardians of the public peace were 

 Spaniards, appointed by the City. Nowa- 

 days policemen are assigned to the duty of 

 guardiar.s of the night, and each Legation has 

 policemen on duty, a courtesy of the Cuban 

 Govenunent. Policemen on day a.nd night 

 rounds are jiow the guardians of the peace and 

 protectors cf the city and suburban towns. 



However, private watchmen are sometimes 

 employed in the subiu'bs. They are usually 

 natives cf Spain, and wear a cap with a 

 leather ba.'id to de;:ote their calling as well as 

 their badge of office. They carry a stout 

 cudgel and are accompanied by a watch-dog. 

 These private watchmen are supposed to 

 be on their beat from nine o'clock until day 

 break, but in many cases, they are not visible 

 except on the days they come to collect a dol- 

 lar a month, their usual stipe.-id. 



There is a motion before the House to abol- 

 ish this nightly service, as useless and unde- 

 sirable. 



However, sometimes a shrill call by a 

 whistle will summon aid either to help quell a 

 fracas, or hold up a dark marauder, attempting 

 to break into a house. Cuban dweUings are 

 safeguarded with iron bars and strong, mas- 

 sive doors, but some houses cf modern archi- 

 tecture have light iron scroll work, instead of 

 bars, and doers, easily broken open, and 

 burglars break in while the inmates are asleep. 

 A favorite method of these criminals is to 

 waft a handkerchief saturated with choloform 

 which stupifies the sleeper, and then the 

 burglar has time to cirry off his booty, while 

 the private watchman is taking his forty 

 uinks. 



The j)olice force in Havana for traffic was 

 established by Gen. Armando Eivas, ^who 

 improved the conditions greatly while he was 

 Chief of Police. There are now police, mounted 

 policeme.n, and policemen on foot. Their 

 uniforms are neat and natty and they wear 

 helmets, and wield a club. They are kept on 

 the alert, especially in the crowded narrow 

 streets of the capital. It is estimated that 

 six thousand automobiles and motoring 

 cars traverse Havana daily. Since the Ford 

 Agency has been established, automobiles can 

 be hired for twenty cents a trip in town and 

 for thirty five cents a trip in the Vedado.
