The existing plantations on canals and bunds were maintained in good order. Tree
planting on the Jamrao is being actively pushed on.
No Egyptian cotton was grown in the Indus Left Bank Division. Observations were
made on the number of waterings taken by indigenous cotton and the interval between
waterings. On inundation canals the waterings ceased about October. On the Jamrao
perennial canal, some were continued until January. Space does not admit of fuller details
in this report.
The outturn was very good and with the price»of cotton still ruling., abnormally high, the
crop was a most profitable one.
