The total amount of rubber that wasbrought to the markets in the year endingJune 30th last was 46,750 tons. Of thisamount Brazil produced tons, or a l)opulation and the consequent necessityo! carrying food supplies everywhere. Inall the vast rubber regions of Brazil it isestimated that there are only 140,000 in-habitants. The rubber districts that thusfar have furnished the supply are becom-ing exhausted and the total productionlast year was less than in the |)reccdingyear. In .Africa there was until recently onlyone region which had been very conspicu-ous as a rubber producer. This was thePortugese colony of .Angola, which in1889 .sent to the 1,728 tons, whilethe Gold Coast and Lagos together fur- r. Lacomotive Engineering FIRST BUILT IN NEW JERSEY. diameter. The outside of the hubs, whichwas 18 inches diameter was highly pol-ished, and the same practice was followedwith the hubs of the truck wheels. Thelatter were 31 inches diameter. This locomotive was placed on the roadfor trial August i, 1837. and made itsfirst trial passenger trip to Madison. Sep-tember 13. 1837. The first regular pas-senger trip was made from Newark toMadison ten days later. We understandthat the boiler carried was about100 pounds per square inch. It is interest-ing to make comparison between thepower of this engine and that of some ofthe monsters that have been turned outwithin the last year. liitle more than half the entire share was 19,800 tons, leavingonly 2,200 tons to be supplied by the restof the world. India furnished 495 tinsand the balance of the supply, 1,705 tons,came fr
