CHAPTER XI.
EXPERIMENTS BEING TRIED OUT ON OUR DAIRY FARM.
On our farm we are equipping to produce certified milk. This will be a new business for us. When we have had more experience along this line we may write up the results for publication. However, none of our experiments are far enough along now for us to be justified in giving the results as final.
Those things which would probably be of greatest interest to farmers are our small grain elevator, the layout of machinery to shell corn, grind feed, cut and re-cut alfalfa and our facilities for handling manure. We use electric power which, so far as we know, is the most satisfactory power where it is available. The motor requires no firing up as does a steam engine, and no tinkering such as goes with the use of gasoline. The motors generally run when you want them to and as long as you want them to and give very little trouble.
Showing arrangement of machinery. The conveyor to the silage blower is just below the floor. Silage or cut hay drops from the ensilage cutter to this conveyor. Opposite the ensilage cutter is the feed grinder into which runs the grain spout from the corn sheller. The ground feed also flows to the conveyor and by shifting the spout of the corn sheller the shelled corn will go to the conveyor without being ground.
Rear view of the barn showing the arrangement of silos. The blower pipe for the ensilage cutter will extend through the barn and with a long arch swing around from one silo to another.
Our ensilage cutter is permanently installed at one side of a driveway in the barn. It will fill three silos without re-setting. By the use of a re-cutting attachment with the ensilage cutter we make finely-chopped alfalfa of all the stems that the cows will not eat. Cattle will eat these stems after they are cut up fine and they make excellent feed for our delivery horses. The blower (made by the American Harvester Company of Minneapolis) which we use for elevating is separate from the cutter. It is also used to elevate shelled corn, oats and ground feeds to bins overhead. The conveyor to this blower is slightly below the floor level so that ground feed will run from the feed grinder to the conveyor, so also will our shelled corn, or oats that we are unloading from wagons, and the re-cut alfalfa. Everything goes to the blower and is distributed to different bins by turning the spout. An ordinary ensilage cutter can be used as an elevator for grain just as well as the separate blower that we use.
Our system of hauling manure is probably more original than our arrangement for handling feed. We do not shovel the manure out of this barn, neither do we push it out. We wash it out with a two-inch stream of water. The gutters slope from the ends of the barn toward the center, being two feet deep at the center of the barn and one foot deep at the ends. Over these gutters we have cast-iron grates to prevent a cow from slipping down. A ten-inch tile leads from the gutter to a large cess-pool outside of the barn and from this cess-pool we pump the sewerage along a ridge to the highest ground of the farm and irrigate it down over the fields. We have an abundant water supply available, cheap power, and hope this plan will prove a practical means of handling manure. So far it has been a very easy matter to flush the manure from the gutters and our sewerage pump throws 200 gallons per minute through a four-inch pipe up the hill as far as we want to go. We use cut straw for bedding and run plenty of water in with the manure so the pump will not clog. The picture of the pump shown is taken from the catalogue of the American Well Works and does not represent our cess-pool but is similar to the outfit we use.
