X-RAY AND THERAPEUTIC EQUIPMENT 
2 
nt 
The standing of the medical profession is high in the Netherland 
East Indies, and consequently there is a good but limited market 
for X-ray and therapeutic equipment. Prior to 1927 German manu- 
facturers controlled this market. In that year, however, an Amer- 
can firm making this class of equipment appointed a large engineering 
concern as its representative and assigned a factory representative 
to the Netherland East Indies to work with its agent. The results 
have been encouraging, and at present the agents have realized the 
possi of the line to the extent of carrying a representative 
stock. 
Despite the fact that the prices of the American equipment are 
more than double those of similar German and Dutch equipment 
(the latter has only recently been introduced), its popularity is 
increasing because of various features not included in other machines 
and because of the policy of the local agents in giving free service. 
Sales have been helped considerably by demonstrations in charge of 
a trained factory technical man before prominent Government offi- 
cials and physicians. American firms manufacturing this type of 
equipment and desirous of marketing it in the Netherland East 
Indies could hardly hope to do so by correspondence alone. The 
3 companies that at present control the market, 1 American, 
1 German, and 1 Dutch company, all have their own salesmen 
in Java. 
ELECTRICAL COMMUNICATION 
TELEPHONES 
Local telephone companies have been in operation in the Nether- 
land East Indies since 1884, when private companies opened ex- 
changes in Batavia, Surabaya, and Semarang. These plants were 
later taken over and operated by the Government, which at the 
present time owns and operates all the telephone service of the islands 
with the exception of the lines owned by the Deli Railway Co. on 
the northeast coast of Sumatra. At the end of 1928 there were 45,201 
subscribers to Government telephones. During that year local calls 
totaled 73,000,000, while long-distance calls totaled 2,131,643. The 
revenue from the Government telephone service amounted to 11,219,- 
121 florins in 1928. 
Although experiments have been conducted with American tele- 
phone apparatus and some has been installed in the islands, the 
majority of the equipment comes from Germany. Most of the local 
plants have only simple magneto switchboards. At the end of 1928 
the following types of local plants were employed by the Government 
telephone service: 
Common-battery, multiple-manual switchboards____..___.__..___________
