of which offer the advantages enumerated 

 above. With the Hamel Smith dryer, in 

 order to economize every inch of space avail- 

 able within the drum, the largest dryers are, 

 as shown in the design on p. 386, now made 

 with six large cylinders instead of the twelve 

 smaller ones shown in the original patterns. It 

 will be noted that each cylinder contains three 

 sloping ledges or narrow shelves, which check 

 the fall of the contents, and by dropping them 

 gently towards the next ledge allow the moisture 

 to escape and the air to circulate freely between 

 the portions without harm to the produce 

 (copra, cacao, ground-nuts, rubber-seed, kernels, 

 &c.) inside in the cylinders. The cylinders, 

 thanks to the lifting arrangements and runners 

 introduced, can now be made up to any capacity, 

 but we do not recommend a greater diameter 

 than 2 ft. 6 in., or at the most 3 ft., for though 

 the drum containing the cylinder revolves very 

 slowly (only just fast enough to avoid scorch- 

 ing), a larger circumference would give too 

 long a drop, and would also cause too heavy 

 a bulk to fall over those below, thereby tending 

 to crush and damage them. On the other 

 hand, they can be made any length, so that 

 the six cylinders will hold 10,000 Ib. of green 

 copra, to turn out about half that quantity 

 when dry. Those wishing to have particulars 

 as to price, &c., for these or other drying 

 apparatus, must state what space they wish 

 to be allowed per 1,000 Ib. of green copra 

 or other produce to be dried.
