A TRIAL BALANCE

IT may be interesting, particularly to readers in neutral countries, to give some impressions of the effectiveness of the enemy aeroplane attacks that have been made since the occupation of northern France. It is hoped to succeed in making these observations as nearly objective as is, in the circumstances, possible, and avoid exaggeration in either direction. So many rumours are, of course, in constant circulation that it is by no means easy to sift the reliability of any particular item of information, but by personal contacts and checking several sources against each other it is as a rule possible to arrive at a reasonable approximation to the facts.
