July 27. BokKHARA CLOVER (Melilotus alba). 'The tap root ex- 
tended nearly perpendicularly downwards to the depth of 33 inches. 
The soil was nearly filled with fibrous roots to the depth of 18 inches. 
Branches from the tap root were traced a distance of 18 inches. 
BENT GRASS (Agrostis canina). Roots extended nearly vertically 
downwards, nearly filling the svil to the depth of 20 inches, many 
reaching the depth of 25 inches. The larger roots had numerous 
short branches from 1to3incheslong. Horizontal roots were traced 
a distance of 24 inches. 
July 29. YeELLow TREFOIL (Medicago lupulina). Plants grown 
from seed sown this season. ‘The tap root extended to the depth of 
20 inches. It began to send out laterals at about 3 inches below the 
surface, many of which were traced horizontally a distance of 15 
inches. 
WHITE CLOVER (Trifolium repens). ‘The tap root began to 
branch at about two inches below the surface. Many of the laterals 
extend 9 inches from the tap root. The majority of the roots were 
within 15 inches of the surface. A few were traced to the depth of 
24 inches. 
SHEEP’S FESCUE (Festuca ovina). Fine fibrous roots nearly fill 
the soil to a depth of 12 inches; a very few were traced to the depth 
of 27 inches. The laterals extended about 9 inches on each side of 
the plant. 
July 31. ALSIKE CLoverR (Trifolium hybridum). Plants from 
seed sown this season. The tap root began branching about two 
inches below the surface, extending to the depth of 28 inches. The 
majority of the fibrous roots were between two and twelve inches be- 
low the surface. Laterals extended about 9 inches from the tap root. 
_ Hassock Grass (Aira caespitosa). The most of the fine fibrous 
roots were within twelve inches of the surface, nearly filling the soil 
to that depth. Several were traced to the depth of 33 inches. Many 
laterals extended horizontally a distance of 15 inches. 
REED CANARY Grass (Phalaris arundinacea). Soil well filled 
with fine fibrous roots to the depth of 15 inches; many reaching to the 
depth of 25 inches. A few were traced to the depth of 33 inches. 
Laterals extended about 15 inches from the plant. There was a 
thickened underground stem just beneath the surface. 
TimotHy Grass (Phlewm pratense). Fine fibrous roots occupied 
the soil to the depth of 15 inches; several were traced to the depth of 
34 inches. The laterals were traced horizontally a distance of 12 inches, 
when they became so delicate that they were impossible to follow. 
CucuMBER. © For the purpose of noting the effect of fertilization 
upon the root growth of the cucumber, two short rows of the White 
Spine variety were planted in very fertile garden soil as follows: 
Row No. 1 was planted over a trench containing six inches of well 
rotted compost, covered with six inches of soil. Row No. 2 was 
planted without manure. ‘The rows were cultivated as nearly alike 
as possible. 
Aug. 4. Row No. 1; The tap root extended downwards nearly 
perpendicularly until it nearly reached the manure, when it turned
