Agricultural and Commercial Society, 105 
formed of timbers 4 to 6 ft. long, about 5 ft. to 6 ft. 
diameter, laid across close together, and the animal 
track is made up, either with " fascines " or ordinary 
*' corduroy " cut in the neighbourhood, covered with 
gravel or any other suitable material near at hand. The 
clearing required is inconsiderable and it often pays to 
go round a clump of large trees rather than cut them 
down. The rails are of the **Decauville " type, and the 
rolling stock is so constructed that the cars can be 
converted at very little expense to suit a double-rail 
line. 
The cost of a fully equipped monorail line in British 
Guiana would work out at about £400 a mile at the 
very outside. It has been laid in other countries at 
£250 per mile. In French Guiana a line 80 miles long 
to Carsevenne has been built and is working most 
satisfactorily. Shorter lines have been laid, all giving 
satisfactory results — one in Mexico, 21 miles long, and 
others in Egypt and in Nigeria. 
The paper was left over for discussion at the next

ing the thanks of the Society for their trouble in 
connection with the exhibits for Toronto Exhibition, 
was read and taken for notification. 
A letter from Mr. C. E. Smith, Jamaica, was read. 
The writer wished to correct the price list given in his 
former letter by having the smooth Cayenne pine-apple 
suckers put at £1 10, instead of £2 per hundred.
