Part VIII] Smythies : Afforestation of Ravine Lands 33 
(iv) The number of work units and cost per acre can be naturally- 
reduced if necessary by leaving sheer cliffs unworked (where 
further erosion is not to be checked) and by preparing ridges 
and ditches on steep slopes without soil working in between. 
In any one locality there is a definite maximum area which 
can be successfully tended in the rains ; this has to be borne 
in mind, and considerable variations in labour supply can 
to some extent be balanced by variations in intensity of 
soil working. 
(v) The standard tasks (detailed in para. 6) were found by ex¬ 
perience to represent a good and fair day’s work for the 
labour. Fines for non-completion of task were very oc¬ 
casional. 
These are the chief points worth noting. Their record in this 
note will, it is hoped, prove of value when next famine conditions 
occur, and famine labour is again utilised on a large scale in ravine 
reclamation work.
