soil are represented. sinks figunes YS2a- sands b 
and fig. 33. Sometimes (cf. figure 32a and b) the 
stalk extremity of the jelly-like mass and the 
hollow stalk itself is found to contain moreover 
a few bunches of much bigger more or less 
oblong grains. Besides the stalk sometimes intrudes 
a little way into the jelly-like mass, as may be 
seen in fig. 32a and fig. 33, Fig. 32b shows the 
same jelly-like mass with the broken off stalk, 
which had been fixed in the soil, as fig. 32a; 
in fig. 32b however the extremity of the stalk 
no longer intrudes into the jelly-like mass, This 
intrusion and protrusion of the stalk which passes 
into the jelly-like body 
may happen when the 
jelly-like mass ismoved 
by the water. The 
dimensions of these 
jelly-like bodies are 
Seen in fies 32a and
