ent we shall probably have to utilize Dr. Clothier's services in connection with our co-operative work with the various states in the attempt to meet the shortage of farm labor. but as soon as this eXigency is past it is our pur- pose to allow him to resume his inveS- legations in Arizona, and we shall be very much gratified if his work there shall result in benefit to Arizona agri- culture
 Very truly yours. (Signed) D. F. HOUSTON, Secretary. MlLLET-A CATCH CROP There are many varieties of millets the most common being the foxtail nillets. Of this group the best known is the German millet and very likely { this is the best variety for Arizona. al- though other varieties of the foXtail millets as well as other kinds of this plant have been grown successfully in various parts of Arizona.
 At the reclamation experiment sta tion at Yuma. Goldmine Japanese, and Turkestan millets have made yields fully equal to the yields of German mil let. The last named variety is better known and the seed is easier to get and cheaper The present price being about S7.00 the hundred pounds. The amount of seed to be used varies with the character of the soil. the richer soil requiring a smaller amount Prob ably 30 to 40 pounds should be used for best results in producing first class hay. German millet requires about ninety days to mature. It is a warm weather plant and does not grow very fast in cool weather.
 AS catch crop it has considerable value, as it may be put in with min mum of labor and while it will require frequent irrigation inasmuch as it is a shallow rooted plant, it will pro duce a considerable amount of very fair hay when in many instances there is not time to put in d crop of corn or the grain sorghums
 Alillet can hardly he compared to Sudan grass in value either for hay or pasture, except that the cost of seed ing is considerably less.
 COMMON INSECTICIDES
 Considerable time and money are wasted and crop. losses suffered un- necessarily by farmers and gardeners as a result of improperly used insec- ticides and fungicides Trees and plants are frequently unnecessarily sprayed with the expectation of pre- venting attack by pests in general. While there gre preventives which can be successfully used in some cases. as a rule it is useless to spray without some definite object in view In cases of actual damage by insect pests or fungus diseases the wrong material is frequently selected. Paris green or arsenate of lead. for example. are use less against plant lice or other suck ing insects or against plant diseases.
 A few of the more important insec- ticides and their use are given below:
 Nicotine Sulfate-Sold commercially as Black Leaf 40' Recommended for use in Arizona as spray for aphis and thrips on vegetables and fruits. See Press Circular No. 26. Ariz. Comm. Agr. and Hort. and Timely Hint No. 99, Ariz. Agr. Exp. Sta.
 Coal Oil Emulsion-Home made. Recommended for use in Arizona in emergencies against aphis and other sucking bugs when nicotine extracts are not available It is likely to in- jure foliage of plants especially when hard water is used and the emulsion is emperfectly made. See Press Cir cular No. 25 Ariz. Comm Agr. and Hort
 Poison Bran Mash-Nade with bran, cheap uolasses. Paris green anu finely ground lemons and water Alfalfa meal may be substituted for tn, bran. Recommended for use in Arizona for --~.----.
