With woolly pyrol the results of 

 inoculation were, in the case of one 

 estate, more definite and satisfactory. 

 The experiment plots were each |-acre 

 in area, and from the plot sown with 

 seed that had not been inoculated 330 lb. 

 of green bush was gathered. A second 

 plot also sown with uninoculated seed, 

 but which was ■ watered ' with the 

 culture fluid, yielded 700 lb. of green 

 bush ; a third plot that had been sown 

 with inoculated seed gave 970 lb. of bush, 

 while from the fourth plot, sown with 

 inoculated seed, 1,015 lb. of bush was 

 reaped. It will be seen that in the cases 

 indicated, inoculation seems to have 

 been distinctly beneficial for woolly 

 pyrol. At two of the stations, however, 

 all the plants on the experiment plots 

 were destroyed by caterpillars. No 

 report has yet been received on the 

 trials with alfalfa. 



The Grenada experiments were designed 

 to ascertain (1) whether any benefit is 

 to be derived from inoculation of legu- 

 minous crops on Grenada soils, and 

 (2) whether, by inoculation, leguminous 

 green dressings, such as cowpeas, can be 

 grown under the shade produced by full- 

 grown cacao. The trials were made at 



the Experiment Station, and on six 

 different estates in the island, where the 

 crop under treatment was cowpeas, 

 which were inoculated with a material 

 prepa red especially for this plant. 



At the Botanic Station and two of the 

 estates, the results obtained showed no 

 difference whatever in favour of inocula- 

 tion. At two other estates, the returns 

 from the inoculated plots were slightly 

 superior to those which had not been 

 treated. Finally, on the two remaining 

 estates — Dougaldston and Diamond — it 

 is reported that the inoculated plots 

 gave yields very considerably higher 

 than the untreated plots, although no 

 actual figures are stated. 



Inoculation, however, had no effect in 

 influencing the growth of cowpeas 

 planted beneath the shade of cacao trees, 

 and these failed completely in all cases. 

 The results of the experiments, there- 

 fore, give a. negative reply to the second 

 question suggested above. 



It may be added that the inoculation 

 of sugar-cane plants with Professor 

 Bottomley's culture preparation sould 

 not be observed to have any effect what- 

 ever, either at Antigua or Barbados.
