This machine being originally designed as a malt-drier, a number 

 of other types of malt-drying machines were examined by Mr. Cart- 

 wright, Inspector of the Ministry of Agriculture, while in England. 

 None of the types seen, however, seemed to be so simple in construction 

 and management or to meet the requirements of the case so satis- 

 factorily as Simon's machine. 



The new models of the machine are fitted with an automatic 

 apparatus for ringing bells when the temperature rises too high or 

 falls too low, an improved reducing- valve facilitating the adjustment 

 of the steam-pressure, and a door in the base of the cylinder for cleaning 

 it out when a fresh variety of seed is to be treated. 



This machine has been definitely approved by the Ministry of 

 Agriculture.

(12) Lenzi's Machine. An experimental model of the simplest 

 possible form of seed-heating machine was erected during March of 

 this year in the ginnery of the Banque Transatlantique at Mansura. 

 It consists of a long narrow cylinder, steam- jacketed all round, in 

 which revolves an axle bearing a number of broad propeller blades 

 which force the seed from one end to the other. 



A sample of seed treated at 55 C. showed complete mortality 

 of the worms, but a slight diminution in the gerrmnation of the seed. 

 The actual tests made gave the following figures for germination : 



These seem to show that about 5 per cent of the seed is damaged 

 in the process. This damage must certainly be due to the overheating 

 of a number of seeds that have' remained too long in direct contact 

 with the heating surface. It was observable that masses of seed 

 in front of the propeller blades traversed the lower part of each
