 revolution en nntw with vrrv little tnovement //'/</ ae. The outer- 







most seeds of such masses would consequently remain in contact 

 with the surface of the steam-jacket for a considerable period, as 

 the mte of revolution was verv slow. ( )l)viously. it should lie possible 

 to oven-dine this delect hv keeping the seed in ..... re rapid motion 

 during its \- through the machine. 



Apart from this one remediable defect the machine was very 

 satisfactory. In a. trial the first seed that came through had a 

 temperature of .")("('.. which rose verv gradually and regularly to 

 55('., where it remained constant.

Mocri'x MiK-lmn. Practically identical in principle with 

 the last machine is one designed l>y Messrs. ( 'hristodoiiloii and <!y/i 

 and ei'eeted at the ginnery of Mr. (!. K. .Macri at Xifta. Instead 

 of consisting of a. single long cylinder, steam-jacketed all round, 

 however, it consists of three shorter cylinders, placed one above the 

 other', and steam- jacketed on the lower half only, the upper hall 

 being a lid which can lie removed so as to facilitate the cleaning ol 

 the cvlinders. In each cvlinder i here is a revolving framework 

 which carries on its circumfer. -piral band which propels the 



seed along the cylinder, and a number of longitudinal liars which I 

 the seed in constant motion, the \\hole framework revolving (jtiile 

 rapidly. The seed enters through an automatic feeder at one end 

 of the uppermost cylinder and after passing through the t hive cvlinders 

 is delivered at the other end of the bottom cylinder. An automatic 

 heat-regulator has been fitted, consisting of a mercury thermometer 

 with its hull) in the seed chute, and its stem tittcd with three electrical 

 contacts in such a way that, as the mercury column rises and reaches 

 these contacts, electro-magnets are brought into action and close steam- 

 valves. When the mercurv reaches the third contact the steam is 

 cut of! altogether. The installation actually erected has an output 

 of approximately twenty ardebs per hour. 



At a trial, carried out on June 14 of the current yea.r. the machine 

 was tested with two qualities of seed, firstly with what might lie 

 classed ii.-, good quality commercial seed, and afterwards with very 

 low quality. With the better quality seed the temperatures of
