Tropical Laboratory 
The tropical laboratory at Cinchona, Jamaica, has been 
maintained in readiness for the use of investigators who 
might visit it for the purpose of forwarding investigations of 
various kinds. Eight persons in all have made use of the 
facilities during the present year, and the test of actual use 
shows that the establishment of this laboratory was a much 
needed and very efficient extension of the activity of the 
Garden. 
It has been necessary to make only small expenditures for 
apparatus and supplies for this laboratory during the year. 
The extremely economical manner in which this laboratory 
is maintained is due to the practical and vigorous coépera- 
tion of Hon. Wm. Fawceit, Director of the Public Gardens 
of Jamaica, who acts as the representative of the Garden in 
Jamaica, and who kindly places at the disposal of visiting 
investigators the additional facilities of the laboratories and 
library at Hope Gardens, Kingston, Jamaica.
