It is not to be expected nor did the investigator think that the 
same results would be shown on all soils. It is stated that generally 
“fibrous roots having an abundance of food nearby are more con- 
centrated ” than where the opposite is the case. The soil on which 
these plants were grown is a fertile clay loam to the depth of from 
six to ten inches, resting on a tenacious subsoil of gravelly clay. 
“In roots which penetrate the soil it is only the youngest parts with 
their delicate root hairs and papillae that absorb nutriment for the 
use of the plant. The rates of growth of these roots are probably 
largely influenced by temperature and moisture and hence we should 
anticipate a non-accordance of observations made during different 
seasons or in different climates.” 
Carrot and parsnip seeds were planted in four-inch drain tiles so 
as to prevent the formation of all except vertical roots. These tiles 
were placed upright in the ground, the top flush with the surface 
soil. It was found that roots grew straight down until they came to 
the bottom of the tile (fourteen inches) where a portion of the 
roots continued their downward course and the remainder grew up- 
ward along the outside of the tile, branching more and more until 
within three to six inches of the surface where they extended out 
into the soil in the usual manner. When fertile soil was taken from 
the surface and placed around the bottom of the tile the roots did 
not rise to the extent that they did in the former trials. On this
