of export certificate.^ i.'ssued and of 959,926 in the niunoer of containers certified 
compaiid with the figures for the fiscal year 1936. This decrease was largely 
due to the falling off in the quantities of apples and potatoes exp(»rted under 
certification.

which were exported to 63 foreign countries. Some of the more imp(;rtant com-
