PLATE 36 



View of Field J., Minn. Agr. Experiment Station Fann, showing topography and sur- 

 roundings, looking from plot 6 to the bam which occupies part of plot i. The photo, 

 graph, taken on the morning of February 27, 1918, as the snow was disappearing, 

 shows plot 4 to be slightly the lowest, the two streaks of ice from north to south, marked 

 by crosses, both being on the plot. The water, held back by the snow bank at the left, 

 had frozen during the night.
