World War I, is followed by a passage on Pound's 1939 visit to Washington, D.C. to try to avert American involvement in the forthcoming European war. Much of the rest of the canto is concerned with the economic basis of war and the general lack of interest in this subject on the part of historians and politicians; John Adams is again held up as an ideal. The canto also contains a reproduction, in Italian, of a conversation between the poet and a "swineherd's sister" through the DTC fence. He asks her if the American troops behave well and she replies OK. He then asks how they compare to the Germans and she replies that they are the same. The moon/goddess reappears at the core of the canto as "pin-up" and "chronometer" close to the line "out of all this beauty something must come". The closing lines of the canto, and of the sequence, "If the hoar frost grip thy tent / Thou wilt give thanks when night is spent", sound a final note of acceptance and resignation, despite the return to the sphere of action, prompted by the death of Angold, that marks most of the canto.

Here he began to entertain writers and academics with an interest in his work and to write, working on translations of the Confucian Book of Odes and of Sophocles' play Women of Trachis and two new sections of the cantos; the first of these was Rock Drill. The two main written sources for the Rock Drill cantos are the Confucian Book of Documents, in an edition by the French Jesuit Séraphin Couvreur, which contained the Chinese text and translations into Latin and French under the title Chou King (which Pound uses in the poem), and Senator Thomas Hart Benton's Thirty Years View: Or A History of the American Government for Thirty Years From 1820–1850, which covers the period of the bank wars. In an interview given in 1962, and reprinted by J. P. Sullivan, Pound said that the title Rock Drill
