Original copies in printed paper covers are filmed beginning with the front cover and ending on the last page with a printed or illustrated impres- sion, or the back cover when appropriate. All other original copies are filmed beginning on the first page with a printed or illustrated impres- sion, and ending on the last page with a printed or illustrated impression.

Fremiently, younj; self-fed pigs on pasture neglect thi; green food for the more palatahle aild easily ohtained meal. Prevent this hy arranging two hinged . uvers which may he dropped over the troughs. By occasional use of these, Mr short periods, the pigs are forced t.) forage. Meals and Mixtures for the Self-feeder. From a inechanical .standpoint, any mixture of whole or ground grain )r mill feeds may he successfully self-fed. The graui ration may :»' he fed mixed or with each c(unponent part Separate, allowing the i)ig to eh..os(> for hims('lf. He can do this. Such a plan recpiires partitions in the feeder. J'ur young i)igs Mr shoats, any of the following mixtures will he found suitahle provided all hulls are fairlv finely ground: — l'.

Where such earn. he ohtained, the addition of tankage, meat, or hlood meal is reroiumendei' Tankage may hest he fed from a separate f.rder or hy partitioning off a small section of the regular structure. Allow the pi'is to meet their own requirements. The Construction of a Self- Feeder. (See cross section). j}agf_ — The feeder .should rest upcm two pieces 2 inches hy 4 iiiches running iigthwise, placed Hat. These may act as runners. On tl niches by 4 inches to carry the structure. ,S/,/(-.s.— Make the sides of 2 inches hy 3 inches sheathetl inside rcssed lumber, as shown. (j(il(,_ — 'Pw,, arrangements of the feed-gate are shown. Thin is the ini i)ort(iiil '•li of the feeder. XoTE. — To ensure the constant feeding of the meal, some means of agitation - necessary. Otherwise the contents will block close to the bottom. Make the iron hands (two on each siile) connecting tlie control slide at the -itom, with the thumbscrew at the top, ofliyht strap-iron | inch thick by I inch . le. When the meal ceases to How, the pigs naturally root or nose toward source of suppiv, and being able to move this flexible slide, which in turn i: ~ses upon and breaks the meal hlockad( — they are rarely left with a "dead" i-feeder. To prevent the pigs forcing the board too far in, it is, of course. inside at either end of t'ach brnle. Allow ai>uut J-ini h lay pieces of hv !-inch iry pl pl v between the slide and the cleat. Th(> second iirranKi'incnt shown is siniplf, consistinn of a section of the Kate hinjiinn inward. This the pijcs inaj- root aniiinst, eausinK it to l)r('ak any meal stoppage. Possibly the first described arrangement will be found most satis- factory. Feed Troughs. — The front of the feed troughs consists of one piece 4-ineh by 4-inch (two pieces^2-inch by 4-inch). Tv.o pieces 2-inch by 2-ineh will be l)etter for young pigs. From this front an; phiced 2-inch by 2-inch divisions, 12 inches apart, running up to a 1-inch by 3-inch piece laid al >ng the sides as shown. For general use, a trough width of not more than 9 inches is recom- mended. Roof. — The roof is laid on 1-inch by 3-inch battens, and CDvered with read , roofing. Tile hinging arrangement shown is simple, and prevents leaki .<■ at the peak. A pn^p should hv supplied to hold up the door, or roof wl) filling. It is best to continue the overhang of the cover so that the drip may i' affect the troughs in wet weather. Skle. — The width is shown in the drawing. The length will depend number and size of the pii^s to be fed. .V (i-foot feeder (12 feet of trou. commonly used size, and will feed up to twent.v-five young pigs. CoKt. — Built of new lumber the cost should not exceed ?!() lumber preferably, and giv(> the exterior a coat of paint.
