According to a communication from the American Consul in Tegucigalpa (Honduras) ) as 
a considerable amount of turpentine oil is produced in that district, and more could be . 4 
produced if the market conditions were to warrant it. Experimentally the oil has been — 
shipped in iron drums (gasoline tanks), but it was found that the oil is affected by the = 
-iron®). As much turpentine oil is used in the Panama region, the producers are trying — 
to ship their oil in that direction, but the freights will have to be reduced to make it pay. 
From a communication by the London Imperial Institute °) we gather that ‘the 
- turpentine distillation plant erected in Shahdara (British India) has been destroyed by 
floods and that a new factory has been constructed at Sallo railway station, about 
- 8 miles distant from Lahore. From 5600 cwts. of crude turpentine the Shahdara plant 
: had produced 8525 gallons of turpentine oil and 3303 cwts. of colophony during the 
first eight months of the fiscal year 1913/14, whereas in the year 1912/13 12941 gallons 
of turpentine oil and 5515 cwts. of colophony were obtained from 7500 cwts. of turpentine 
The average price realized for turpentine oil was 2/6 per gallon, and 13/2 per cw 
| for the colophony. Tappings carried out in the Rawalpindi and Kangra divisions yield 
i 11358 cwts. of turpentine in 1913 against 8437 cwts. in 1912. a
