cannot be understood by filtering local experiences through local states of mind. They can be known only by controlled reporting and objective analysis. And just as the head of a large factory cannot know how efficient it is by talking to the foreman, but must examine cost sheets and data that only an accountant can dig out for him, so the lawmaker does not arrive at a true picture of the state of the union by putting together a mosaic of local pictures. He needs to know the local pictures, but unless he possesses instruments for calibrating them, one picture is as good as the next, and a great deal better.
The President does come to the assistance of Congress by delivering messages on the state of the Union. He is in a position to do that because he presides over a vast collection of bureaus and their agents, which report as well as act. But he tells Congress what he chooses to tell it. He cannot be heckled, and the censorship as to what is compatible with the public interest is in his hands. It is a wholly one-sided and tricky relationship, which sometimes reaches such heights of absurdity, that Congress, in order to secure an important document has to thank the enterprise of a Chicago newspaper, or the calculated indiscretion of a subordinate official. So bad is the contact of legislators with necessary facts that they are forced to rely either on private tips or on that legalized atrocity, the Congressional investigation, where Congressmen, starved of their legitimate food for thought, go on a wild and feverish man-hunt, and do not stop at cannibalism.
