TICK INFESTATION IN COASTAL TRACT OF NORTH CANARA 303
It is a belt of the country on the Arabian Sea about 110 miles from north to south
and from ten to sixty miles from east to west. Central Kanara is a country of great
richness of scenery and includes three belts: the coastal tract with broad winding
lagoons, rich plains and wooded hills running to the sea; the central belt of the
lofty Sahyadris (Western Ghats) covered with magnificent forests; and an eastern
upland which is wild waving and thickly wooded in the west and in the east passes
into a bare land and thickly populated plain. A somewhat broken and irregular
range of central hills divides the district into two parts; the Up-ghats and the
Below-ghats. The investigation of ticks was carried out in the latter part of the
country.
