S18) REPORT OF DEPARTMENT OF BACTERIOLOGY OF THE 
The two valid objections to the use of soil for inoculating 
purposes are the initial cost of the soil and the danger of in- 
troducing pests. Both of these objections are successfully met 
by the above plan of experimentation. The bag of soil required 
for a half-acre can usually be obtained from a neighbor or from 
the Experiment Station and if purchased in the market may 
be had for one dollar and the cost of transportation. After such 
an experiment, in case it is found that inoculation is necessary, 
the experimental plat will furnish enough soil to inoculate a 
number of farms, if desired. Again, the amount of land which 
is originally inoculated is small and if results show that dodder 
or any other pest has been introduced the problem of combat- 
ting it is not a serious one. While it is undoubtedly true that 
pests may be distributed by soil our correspondence and obser- 
vations extending over a number of seasons have not brought to 
light a single instance where this has actually occurred. 
SUMMARY OF INOCULATION EXPERIMENTS BEGUN IN 1907. 
The results obtained from the 86 experiments which were 
properly conducted and reported are given in Table I:
