Also the main engine was repaired, including the boring of the cylin ders, fitted with now pistons, and converted to back-pressure use, ex- hausting into the two low pressure- boilers, no longer worked for steam generation,.
The Not Result.
The net result was to cut the total coal bill down about 50% since the 30 tons burnt on the low pressure boilers was saved, and the high presatre boilers only took about the same amount of coal as before,
in spite of all the power being gen-
rated, practically as a by-product.

Governmental aid is considered more necessary now than ever before. As a result of the use of motor

Mileage and Motor Vehicle Registration.
I 1030 the Netherland East In dies had about 35,900 miles of high ways, of which 24,850 were macadam (2,500 miles with bituminous aur- face), 30 concrets and brick, and 11,050 low-type, earth, sand-clay, or gravel, graded and drained. The road mileages of some of the larger islands are reported as follows: Java. 15,500; Sumatra, 11,400: Borneo, 1,400; Moluccas, Bali, Lom hot, and Timor, 3,060..
There were 84,783 motor vehicles registered in Netherland East Indies at the end of 1930. Of these, 63,735, ware passenger cars, 6,838 busses, and 14,510 trucks.

During these two years concrete mixers valued at $18,220 were also exported from the United States to Netherland East Indies. Because of the im portance and need of good roads, this ahould eventually be an attrac- tive market for road-building ma- chinery and traotors. With cheapness of hand labour, however, greatly increased use of mechanical equipment is not to be expected in the near future.
