advantages over the latter, and the majority of machines 

 now being sold are equipped with Blowers. We mention 

 below some of the features that have served to bring the 

 "Ohio" Monarch Blowers to the notice and favor of farm- 

 ers and dairymen so rapidly. 



The Blower Machine is quickly set up, taken down or 

 moved, as all that is necessary is to remove the pipe, 

 (which is in sections of various lengths from four to 

 ten feet as desired), which requires but a few moments. 

 This operation requires but little time as compared with 

 that occupied in setting up or taking apart the chain 

 elevator. 



The Blower Machine is clean in operation, placing 

 all of the corn in the cilo and there is no litter around 

 the machine when the filling is finished. 



The action of the fan paddles is such that the corn 

 is made much finer, and it therefore packs closer in the 

 silo, thus enabling more fodder to be stored in the silo; 

 the corn is all knocked off of the pieces of cobs and dis- 

 tributed through the cut fodder better, and the pieces of 

 the heavy butts and joints are also split and knocked to 

 pieces, all of which reduces the silage to a fine condition 

 so that it is eaten up cleaner by the stock, 



The fan or blower device is also likely to be more 

 durable than the chain elevator. 



Many have been skeptical as to the ability of the Blower 

 to elevate the material as rapidly as the "Ohio" Machines 

 cut it. This proposition, however, has been proven en- 

 tirely feasible and successful, and there positively need 

 be no fear on this point if the following points are kept 

 in mind. 



The machine must be run at the proper speed as 

 recommended by the manufacturers. A fan can only 

 create a sufficient blast by running fast enough to force 

 the air through the pipe at the' rate of nine or ten thou- 

 sand feet per minute. Green corn is heavy stuff and re- 

 quires a strong current of air to carry it through 30 or 

 40 feet of pipe at the rate of 10 to 30 tons per hour. It
