treatment to other infected areas. This and other pests, such as
_Myelois ceratoniae_, _Cossus liniperda_ (a lepidopterous boring insect),
a species of _Mycetiasis_, and a small hymenopterous fly which has
lately appeared and is now under investigation, have, no doubt, checked
production. The attacks of _Cecidomyia_, when serious, reduce the yield
by 80 per cent. or over, and normally may lessen it by 40 to 50 per
cent.

Much damage is also caused by rats (_Mus alexandrinus_), which gnaw the
bark of the branches, causing them to dry up. Their destruction is
encouraged by Government by the payment of 1 cp. per tail.

Carob gathering commences about mid-August and lasts for about a month.
The beans are knocked down with long sticks, put into sacks and brought
into store, or heaped up in the open air, where they often remain for
several weeks. This is a safe procedure, as there is little rainfall at
that season, and what might fall would not harm the beans, which would
quickly dry again.

It is not easy to estimate the yield per donum of carob trees, but
assuming that the trees were planted 30 ft. apart, and there were 16
medium-sized trees to the donum, the yield would average somewhere about
1,260 okes to the donum. The yield varies from year to year, a good year
generally being followed by a moderate year. The fruit may be destroyed
by frost in January and February, knocked off by hail-stones in March
and April or scorched by hot winds in May or June. A full-sized,
well-cultivated tree can give up to 720 okes. Taking good and bad years,
the value of the annual produce of a medium-sized tree is 5_s_.

Carobs are sold by the Aleppo cantar of 180 okes, and the normal price
may be put at from 13_s._ to 17_s._ per cantar delivered into store.

Carobs are weighed on export and the tithe is taken in money from
exporters at the Customs House.

The following table shows the export of carobs during the ten years
ending 1913-14:
