sistently and consistently advocated the growing of hairy Peruvian alfalfa in this valley.
 ReallZlnS the enormous loss to -armers that occurs from the damage of small grains by the various smut dis eases, this farm has consistently ad- yocated and practised the control of smut by means of the formaldehyde treatment. On the farm today you will find an excellent demonstration of the control of smut
 During the last few months. con- siderable interest has been manifested m the lnocuiation of various legumes. l1lkeWise considerable interest has been manifested In the planting of legumes with cotton and other crops. Claims have been made that such Iegume paintings, particularly if these legunes are lnoculated, results in materially in creased yields of the accomnanvine crop or companion crop. We do not at the present time have definite resnlts ooffer you covering this subject. now ever we have on the farm a consider able number o departments in which legumes have been planted with cotton and with other crops. In some cases legumes were inoculated and in some other cases they were not inoculated.
 "As a direct comparison cotton has peen planted with the same snacinp that Is gwen when planting with le- gumes, but the legumes have been omitted. This test is intended in nrova whether or not the increased yield claimed from the legume planting is not due, at least in part, to the in- creased space and light given the cotton.
 "Of late considerable interest has been manifested in fertilizing cotton. You will find on this farm at the pres ent time ten acres of grounS devoted to a rather complete fertilizing test. In this test cotton without fertilizing is compared with cotton that has been fertilized with ordinary barn yard ma nure at various rates and with cotton 1 that has been fertilized with acid phos- phate, with nitrate of soda, with cotton seed meal, with complete commercial fertilizer, and with various combina- tions of these fertilizers. These nlots are not far enough advanced today to show great deal, but your inspection l of the plots is invited.
 | These are not the only lines of work in which this farm is interested. Time l does not permsr a. detailed discussion of many of the experiments. It is suffi- cient, perhaps, to say that carefully planned work is under way to deter mine the value of green manure. on the land itself, and on the crops that follow the application of green manure. Ex- periments are under way to determine the relative yield of wheat on the ground that is cropped continually to
 wheat compared to wheat in two and
 three year rotations and compared tc
 wheat that is treated to both barnyard manure and fertilizer Experiments are
 under way to determine the best dates
 for planting cotton and the best spac-
 lngs for thinning cotton. Likewise, ex- per1ments are under way to determine
 the best methods of irrigating cotton. | "A silage feeding test was conducted this last winter comparing the value of silage compared with certain other feeds for ewes at lambing time. l Last summer this farm constructed i the first metal lath cement plastered 1 sllo in the state and we hope vou will examine this silo today.
 "The Experiment Farm belongs tc you farmers and citizens of this state l We want to solve the problems thai you want solved. We will thank you always for constructive criticism ana | for suggestions of work that you would ! like to have us undertake. We ask your 1 co operation and we invite you to visit the farm at any time
