1 . Food consumption of school children in I'elation to health. Assistant Professor 

 E. S. Davies. A survey study carried on in three rural towns, with the cooperation 

 of the schools and of the State Department of Health.

7. Studj^ of the factors influencing heading of greenhouse lettuce. Assistant 

 Research Professor V. A. Tiedjens. A report of one phase of this study was 

 printed as Scientific Contribution No. 31, "Stimulation of Plant Growth by Means 

 of Electric Lighting." 



8. Study of conditions affecting the production and vegetative propagation of 

 asparagus. Assistant Research Professor V. A. Tiedjens. Some of the results 

 of this study are reported in Scientific Contribution 36, "Some Physiological 

 Aspects of Asparagus Oflacinalis." Supplements the earlier work of the Experiment 

 Station in cooperation with the United States Department of agriculture in breeding 

 the rust-resistant Washington asparagus. It was found that this asparagus, 

 although of ver\^ high qualitj^ was quite variable between hill and hill, which gave 

 rise to the attempt to propagate vegetatively and thus retain the best produced by 

 seed. Encouraging progress has been made, although the method is not yet 

 ready for general distribution. 



9. Investigation of susceptibility to corn borer attack of varieties of sweet corn 

 as influenced by time of planting. P. W. Dempsey. Carried on on the basis 

 of a five-year program and fuianced cooperatively by the Corn Borer Laboratory 

 at Arlington, supported by the United States Government, and the Market Garden 

 Field Station. Marked differences in susceptibiHty to attack are associated 

 with time of planting; but thus far injury-free dates have not been established. 



10. Variety improvement through seed and root selection : (a) The improvement 

 of beets {Beta vulgaris) through selection of roots and seed production; (b) The 

 improvement of carrots {Daucus carota) through selection of roots and seed pro- 

 duction. Assistant Research Professor V. A. Tiedjens. 



11. Control of red spiders on cucumbers in greenhouses. Assistant Research 

 Professor W. D. Wliitcomb. Merged with the project immediately following, 

 owing to the fact that both insect and disease have to be cared for in a single spray 

 or dusting.

 a combination spra^'. Assistant Research Professor W. D. Whitcomb and Assistant 

 Research Professor E. F. Guba.
