similar to those of the checks, while both the two- and the six-ton applica- 

 tions of lime decreased the yields. The Paxton soil had the greatest per- 

 cent decrease while the Melrose showed the least effect from any of the 

 treatments.

Preservation of Carotene in Silage by the 

 Use of Sodium Bisulfite As a Preservative 



The effect of sodium bisulfite in the preservation of the carotene con- 

 tent of timothy, red clover, and alfalfa, where used as silage, was investi- 

 gated. Timothy showed very little loss from the treated sample and 20 

 percent loss from the untreated sample. Alfalfa had four percent loss on 

 the treated sample and ten percent loss on the untreated. Red clover was 

 a poor third with a 27 percent loss on the treated sample and 50 percent 

 loss on the untreated. Further samples of timothy, red clover, ladino, and 

 brome grass are still in the silo for later analysis.

Marketing Mixed Grain Feed 



Observations have been made concerning two phases of mixed feed 

 handling : 1 . the problems involved in delivering grain from store or freight 

 car to the farmer's feed room, and 2. the storage, handling, and feeding of 

 mixed grain at the farm. 



The delivery of grain in the retailers' truck to the feed room on the 

 farm has become an accepted practice. Data have been obtained from store 

 managers concerning delivery routes and practices. In addition, detailed 

 time and ol)servation records have been made while traveling with truck- 

 men on their delivery routes. 



Most stores have regular weekly truck routes and will deliver one bag 

 oi more of grain to any location within their normal trade area. On some 

 routes, the truck mileage and labor involved in delivery of small lots to 

 manv scattered locations represent high costs. Due to keen competition 

 among grain dealers, each attempting to maintain or expand his total 

 volume of sales, certain farmers demand and receive extra services which 

 place an additional cost on the delivery system. For instance in a few 

 cases grain is delivered to grain rooms on upper floors of poultry houses. 



The deliverv of grain by the store may be good farm management in 

 most cases because the operator can use his labor more advantageously at 

 the farm. However, since frequent delivery of small lots of grain to iso- 

 lated places and the special services to some farmers result in large total
