clover crop crowds out weeds. A pasture, in many cases, is good to 

 reduce the number of weeds. 



'i. Use Due Care With the Threshing Machine. See that the machine 

 is always cleaned when passing from one farm to another. Quack 

 grass, mustard seeds are often carried from one farm to another. 



o. Use eare in trans pi atitifig hay, grain straw and manure from one 

 farm to another, or from the city to the farm. Quack grass and other 

 weeds are frequently carried in this way. 



6. Utilize sheep for the destruction of weeds. 



7. Use some vigorous and thick, groicing crop to crowd out weeds. 

 For this purpose sorghum, clover, or millet is good. 



8. Give thorough and clean cultivation for corn. Cultivate as long 

 as the corn crop will permit. 



0. As far as possible plow small grain crops and corn fields in the 

 fall. This will destroy many annuals whose seeds germinate in the 

 fall; especially valuable for winter annuals like shepherd's purse and 

 peppergrass. 



10. Use iron sulphate for annual weeds like mustard, ragweed and 

 smartweed. 



11. See that all weeds in xoaste places are removed. This will pre- 

 vent their spread to cultivated fields. 



The unlawful weeds of Iowa are quackgrass, Canada thistle, cocklebur, 

 wild mustard, curled dock, smooth dock, buckhorn, wild parsnip, horse 

 nettle, velvet-weed, and burdock. 



In this connection permit me to call your attention to a circular, "Un- 

 lawful Weeds of Iowa," which you may obtain by writing to Prof. C. F. 

 Custiss, Ames, la.

Members of the Iowa Aberdeen Angus Breeders' Association: 



Just at this time of year you are no doubt questioning yourself and 

 others as well as to what this year is going to bring in the way of sales 

 of purebred livestock of your particular breed. I think you should be 

 congratulated that you have a purebred herd gathered together. I am 

 of the opinion that this year will bring an unprecedented demand for 

 pure-bred bulls and breeding stock of all ages. 



There seems to be a stimulated interest on the part of the farmers all 

 over the state to grow more beef. This is really the best sign. Besides 

 the intere'st in growing more beef, manifested in this state other 

 states, particularly in the south, are just beginning to realize their pos- 

 sjbjjitias IB the grpwin^ of beef.
