This conclusion is based on semen evaluations of 232 Hereford.

Minutes after you spray, every fly that’s been hit will be dead or dying. When DI- BROM hits ’em, they stay hit. Even if they’re re- sistant to other sprays DIBROM is registered to spray over and around cattle. In fact, Dibrom in emulsified form is even safe to spray on food crops, up to four days of harvest It’s easy to use, comes to you ready-mixed and gives you real economy. Sure, it costs a little more than your pyrethrin sprays, but you’ll find that it gives a lot better kill. So when all is said and done you wind up getting back a lot more of the money that flies have been costing you in reduced milk and meat production. Come in and see us . . . we’ll be glad to show you how to go after flies like you mean it ORTHO DIBROM, T M. Reg. U. S Pat. Off.: Ortho, Dibrom.

Within 3 days of the last evaluation, these bulls were mated to feedlot heifers. Results of natural matings and of the semen quality tests were consistent in comparing groups of bulls. One group of 10 “good” bulls successfully bred 67 percent of the heifers to which they were mated A gioup of 5 “poor” bulls demonstrated only 45 percent feitihty When applied to individual bulls, the “good” or “poor” labels were meaningless.

Hiestond & Co., Inc. plaitic bags just before lear* ing. If there are many plants, place them close together with a large plastic bag over them. Tuck the bag under the pots so the plants are complete* ly covered. This procedure keeps the plants in a humid atmosphere and prevents water evapora* tion from the soil. The plastic-covered plants must not be placed in the sun, Dunham warns. They would bake to death. Instead, put the plants away from the sun or in the basement. There may be a few yel lowed leaves on the plants when you return home. But with normal care, they will soon recover.
