Auburn, Ala, May 17.-(Special)-Th glowing promise of $4 a bushel for corn is held out to Alabama farmers in a bulle- tin produced by Prof. Dan T. Gray, J. w. Ridgway and E. R. Eulaly of the Ala tama Polytechnic Institute, after three years experimental work in swine pro- auction. The corn, to bring the marve- lous price, is not sold as corn, but as pork, after having been fed to hogs.
 The bulletin, whiSh is being widely dis tributed among the stock raisers of the state, probably will bring about the ter imitation of the old system of feeding corn alone to hogs for fattening. The re- narkable results attained by the experi- mentors with soy bean grazing and tank age along with the corn ration for hogs stand for themselves in denunciation of the "corn-only" ration. The experiment ters, however, draw no conclusions, nor set any rules; they announce in the bulle- tin the results of their work, and only that. A summary of the bulletin is:
 When corn was fed alone, unsatisfac- tory results were always secured; whep corn was supplemented with soy bean pasture, satisfactory results were se- cured.
 When corn was used alone, the average daily gain for each hog was only .375 of a pound When soy bean pasture was grazed along with fourth, half and three -fourths ration of corn, the average daily gains were raised to 1.102. 10o6 and i. .329 pounds respectively.
 Six hundred and nine pounds of corn +o ,,oalxa 1nn hounds of nOrlS when the grain was fed alone. When soy bean pasture was grazed with fourth, half and a three-fourths ration of corn, only 6S, 13s, and 175 pounds of corn, respectively, were required to make the same amount of pork.
 When nothing was fed except corn, each 100 pounds of pork cost s7.6l. When fourth, a half and a three.fourths ration of corn was fed along with soy-bean pasture, the same gains were made for S5 cents, s173, and s2.10 respectively, corn being valued at 70 cents; when the cost of pasture sS an acre, was also charged against the gains, each 100 pounds Of pork was, made at an. expense of $2.5o, sS.S6 and SS17 respectively.
 One acre of soy bean pasture afforded grazing for ten hogs, averaging 4o pounds in weight at the beginning of the test for the following number of days: when a four ration of corn was used, 4S days; when half ration of corn was used, 4S days; when three-fourths ration of corn was used, 62 days. The total value of pork made on each acre of soy bean pas turc varied from S25.S4 to s39.l3.
 ."rhese experiments show that it pays to inclose the hogs in a dry lot" accord. ing to the bulletin, after the pasture crops are exhausted. and feed them for q short period of time on grain feeds A ration of corn and cotton seed meal seems to be the most satisfactory feed for this short dry-lot finishing period
 "If it were not for the fact that cotton seed meal is dangerous feed for swine, when fed for more than 30 days at time if would be u very valuable feed to go a,one with corn However. it is an eX- ceedinelv valuable feed when used for short periods of time. In these tests A nounds of cotton seed meal take the place of 335 pounds of corn. The A pounds of cotton seed meal cost o6 cents, the 335 pounds of corn were valued al s4 19: or an investment in cents III cot ton seed meal saved $4.19 in terms Of corn. Tankage and cotton seed meal, pound f9r pound, proved to have practically the same feeding value. Cotton seed meal IS the cheaper of the two, but tankage mas the advantage in that there is no danger of III results when 1t is used.
 Tanlage, a packing house by-prodnc'' saved a great amount of corn. Forty. two pounds of tankage took the place Of 5o5 pounds of corn. The 42 pounds of tank age cost only S4 cents: the 353 pounus or corn were valued at $441 These results were secured with hogs that averaged about 50 pounds, live weight, when the tests began.
 Excellent prices were realized on each bushel of corn when the corn was fed along with soy bean pastures. When corn was fed alone, the usual market prices were not secured. When hogs sell for [ cents pound. each bushel of corn was sold, by means of the hogs, for s1.93 to s433, when nothing but corn was fed, only 64 cents was realized on each bushei.
 The experiments which resulted in the bulletin were conducted on the Alabama
