will constantly be varying around that point but could never go 

 far in either direction, the lagging ctTcct. which is the greatest obstacle 

 to accurate control when the steam -pressure in the whole machine 

 is adjusted, being reduced to a minimum.

(14) Baler's Miu-lthir. -A machine, \\hicli might prove of use 

 in factories in which there is no steam a ailablr. has been proposed 

 by Messrs. Joseph Baker A: Sons, Ltd.. of London. This, in principle, 

 is very much the same as the last machine, but the cylinders through 

 which the seed passes, instead of beiny heated individually by sicam 

 jackets, are heated collectively in a gas-oven. It is proposed to 

 have seven of these cylinders in each oven. The heat is mainiained 

 by transverse rows of burners lying across the interior of the oven 

 at the top and along the bottom. The gas is delivered into these 

 I turners under pressure, a suitable compressor being provided for 

 the purpose. Any kind of gas fuel will do. An automatic control 

 is also supplied.
