. Bulletin. Agriculture. This shows that the amount of KI absorbed in the soaking was large enough as to cause a retarding influence, which was much greater, however, in regard to the production of straw than in that of grains. A field experiment further was made with oats. On 3 plots, each measuring 20 square meters, an equal amount of oats grains previously soaked for two days in water was sown on March 21. On April 15, the young plants had reached 3—4 cm. and were treated now the first time with potassium iodid solution^. The treatment was repeated on Apr. 22, May 7 and 22, and June 10. The

On August 6, the plants were cut, but owing to several storms, some loss of grains had occurred ; hence the final weight is somewliat below the actual production- The straw and grains, unhusked, were weighed in the air dry state with the following result: < "ontrol. \\'eiglit of straw and grains.
