The crop afforded a vety fair test of the work that the machine could do, us it was a heavy one, and owing to the 1-ite rains the flag was pietty hea\y at the foot of the straw. The machine was tinned wt-> the crop, and went along cutting %\ itl.^. y mis hap or stoppage. The M ercer is a novelty in reapers and binders, inasmuch as all canvas is done away with, and Us mechan ism is entirely different from all the machines at present in the market. We have not seen a machine that there ap pears to be so little complication about, or that affords a more reasonable oppor tunity for the remark, " Why was this not thought of before ?" The seat of the driver is at the back of the machine, and there he can manipulate the different levers for the regulation of the parts. The credit of introducing into New Zea land a reaper and binder which appears to have successfully done away with all canvas must be given to the well known firm of Reid and Gray. This, the latest aspirant for public favor, is called " The Mercer," after the inventors and manu facturers. Up to the time the Mercer was invented it was thought impossible to get anything to take the place of can vas for conveying and elevating the grain to the binder, although fortunes had been spent in trying to do so. As the grain is simply lifted up instead of being pressed up to the binder, this renders the draught very light, and is said to reduce the amount of shelling of corn very materially. It also possesses many other advantages in the way of handling the machine. A very novel feature is a little device for holding the whip, which can be operated by the driver at will without removing it from the socket, doing away with carrying a long whip, and leaving the driver's hands free to work the levers. It is difficult in a newspaper report to describe the technicalities of a machine of this kind, and it is only necessary to say that the grain when cut falls on to a sheet steel table, in which are slots through which teeth project.
