THE SEASONS IN GUIANA, 7 
June to August. In both fruits the average number brought 
to market was greatest in July, but the year 1889 was a 
conspicuous exception in the case of the mango. The 
greatest number of baskets of mangoes offered for sale in 
February and March in the other two years was only 45, 
while in the year in question the enormous quantity of 
19,216 baskets were brought to Stabroek Market. The 
previous year was rather dry but a fair supply of rain 
fellin December. Whether this affeéted the crop or not 
it is hard to say, especially in view of the faét that the 
largest crop is usually gathered after the heavy rains of 
May and June. Observations must be made for a great 
number of years before anything definite can be formu- 
lated, meanwhile we can only indicate the lines on which 
researches can be carried out. 
The principal guava season appears to arrive in May 
and June, but this fruit seems to be produced more often 
than twice a year. Ripening quickly it has the advan- 
vantage over many others, some of which can only suc- 
ceed in producing one crop a year. When this takes 
place the season often extends over several months, 
fruit ripening by degrees anda few atatime. This is 
especially noticeable in the mammee-apple which ripens 
from June to September, but is hardly to be found at the 
beginning of the year. 
The Erythrinas flower only once a year from July to 
September. When tropical plants go through one course 
only, the time of flowering seems to differ according to 
the species. The sugar cane flowers only from Septem- 
ber to the end of the year, although fields may ripen 
every month. The avocado-pear flowers in November 
and ripens in July, but individual trees may have one or
