are so few of them, and that they reach this country so 
irregularly. The disease affecting the trees could easily be dealt 
with by careful cultivation and the use of insecticides. The 
Canary people have, however, no idea how to treat them, and 
Orange-growing in the future, if the business is to become esta- 
blished, will have to be done by skilful men from other countries. 
Besides Oranges there are grown a few Lemons, some Citrons, 
Shaddocks, and Limes. None of these can ever attain to the 
importance of Oranges. The Bergamot Orange yields a valuable 
essence from the rind of the fruit. For this purpose the fruits 
are gathered green. Very good Mandarin Oranges are grown in 
Grand Canary. These are easily recognised by the peculiar odour, 
similar to that of the leaves. The skin is very easily detached. 
Tomatos. — The industry in Tomatos in the Canaries is of 
recent date. The first cases were exported in 1887. It has, 
however, increased by leaps and bounds, and is now considered 
in good years to be the most profitable of any. The exports from 
Grand Canary in 1893 were 54,641 cases. In the half-year from 
January to June 1894 the exports were 85,000 cases. It is 
probable that the total exports from Grand Canary and Teneriffe 
will now amount to about 150,000 cases yearly. The sort chiefly 
cultivated is the *' Perfection." The seed is imported every year 
from England and distributed amongst the growers, locally called 
contractors, who undertake to sell the produce to the shippers at 
a certain rate per cwt. The fruit is large and of good flavour. 
The earliest crop ripens in November and December ; the second, 
which is the best, in January to March. The fruit is gathered 
when green, carefully selected into different qualities, and then 
packed in paper with sawdust or peat-dust in wooden cases hold- 
ing, on an average, about 40 lb. The actual cost of growing, 
packing, and shipping Canary Tomatos is estimated at 2^?. per 
pound delivered in London. The fruit is much liked in this 
country, and as it comes over when Enghsh -grown Tomatos are 
not obtainable the channels of trade are kept open all the year 
round. 
The disease in Tomatos in the Canaries is a serious draw- 
back to cultivation. In some seasons the whole crop is lost. It 
is caused in part, at least, by PlLytophihora iu/estans, the Potato 
disease. There is a remedy for it, but systematic action is 
necessary, and the superintendence of Europeans who thoroughly
