APPENDIX A 



The following is a list of the instruments used : — 



I 4-inch tangent micrometer theodolite. 



I Plane table with folding telescopic alidade. 



1 Hypsometer. 



2 Aneroids (R.G.S. pattern). 

 I Prismatic compass. 



1 Astronomical compass. 



2 Half-chronometer watches (R.G.S. pattern). 



Maximum, minimum, wet and dry bulb thermometers ; loo feet 

 steel tape and levelling staff, etc. 



The wooded nature of the country and its extreme 

 flatness rendered any other method than that which I 

 adopted impossible with the time at my disposal. A more 

 rigorous survey would take years to accomplish, and would 

 cost an enormous sum.
