now in use in forty commercial clover seed houses, and by its use farmers 

 have secured better stands from 5 lbs. scarified clover seed than 20 lbs. 

 of unscarified seed per acre. 



3. A new winter wheat has been originated which has increased 

 production considerably. Its chief quality is that it does not winter 

 Jiill like most of the winter wheats of the northern corn belt. 



4. The thorough soil surveys of the State have been extremely useful 

 to farmers, and there is now a soil map, which shows the location and 

 extent of each soil type in the county, which is the real basis of all 

 work dealing with the soil-management problems of the county. 



5. Two-year old steers will make a maximum profit on heavy feed 

 of cheaply-produced silage, with about one-fourth to one-half of a 

 regular full ration of high-priced corn. 



6. It has been demonstrated that self-fed fattening swine should 

 return as high as a dollar a head more profit than when handled in 

 the ordinary hand-fed manner. With the 10,000,000 hogs that are 

 annually marketed from Iowa, this means an increased earning of 

 millions of dollars. 



7. The free-choice system of swine feeding, Avherein the pig h'^lps 

 himself to such feeds as corn, tankage, alfalfa, pasture, &c., has proved 

 so successful that the hog industry is being revolutionized. The scheme 

 saves labour, and economizes feeding. This free-choice system originated 

 at the Iowa Station, and is now practised in every State in the Union. 



8. Bulletin No. 165, copy of which has been forwarded, shows the 

 results of eight years' work in determining the influence of environment 

 and breeding in increasing dairy production. This is the first data 

 published showing the influence of the pure-bred sire, independent of 

 improved methods of feeding and management. In increasing the 

 production from scrub or common cows, the value of the pure-bred* 

 sire as a factor in increasing the production of farm herds is closely 

 demonstrated, as many of the heifers by a high-grade, pure-bred dairy 

 sire have produced 50 per cent, more butter-fat, and 75 per cent, more 

 milk than their scrub dams. 



9. Experiments in Capon production, show that the larger breeds of 

 poultry can be profitably caponized. Capons, compared with cockerels 

 of the same age and breeding, and reared under the same conditions, 

 produce a net increase of 25 per cent, to 40 per cent, above that received 

 for cockerels. 



10. Ear corn, preferably broken, for fattening lambs is the most 

 practical single form in which this grain can be fed. For profitable 

 fattening, corn need be neither shelled nor ground, unless it be towards 

 the end of a prolonged fattening period. 



11. The allelomorphism of horned and polled characters in cattle 

 has been demonstrated, and tests conducted over a period of ten years 

 show that breeders of polled cattle may introduce superior horned 

 animals into breeding herds without danger of seriously losing ground. 



12. Comprehensive tests have been made to show the efficiency of 

 corn, alfalfa hay, barley, oats, gluten feed, tankage, cotton-seed meal, 

 linseed meal, singly, and in various combinations with roughages found 

 on the average Iowa farm, when fed to dairy cattle, beef cattle, and 

 hogs. The results have been published in various bulletins issued by 

 the Station.
