of my friend. His reserve had been always excessive and habitual. I was aware, however, that this very ancient family had been noted, time out of mind, for a peculiar sensibility of temperament, displaying itself through long ages, in many works of exalted art, and manifested, of late, in repeated deeds of munificent yet unobtrusive charity, as well as in a passionate devotion to the intricacies, perhaps even more than to the orthodox and easily recognizable beauties, of musical science. I had learned, too, the very remarkable fact, that the stem of the Usher race, all time-honored as it was, had put forth, at no period, any enduring branch; in other words, that the entire family lay in the direct line of descent , and had always, with very trifling and very temporary variation, so lain. It was this deficiency , I considered, while running over in thought the perfect keeping of the character of the premises with the accredited character of the people, and while speculating upon the possible influence which the one, in the long lapse of centuries, might have exercised upon the other—it was this deficiency, perhaps, of collateral issue, and the consequent undeviating transmission, from sire to son, of the patrimony with the name, which had, at length, so identified the two as to merge the original title of the estate in the quaint and equivocal appellation of the "House of Usher"—an appellation which seemed to include, in the minds of the peasantry who used it, both the family and the family mansion.

On the international side, this year was much calmer than last. Nevertheless, continuing imbalances in the pattern of world trade contributed to intermittent strains in the foreign exchange markets. These strains intensified to crisis proportions, precipitating a further devaluation of the dollar.

The domestic economy expanded in a remarkably vigorous and steady fashion. The resurgence in consumer confidence was reflected in the higher proportion of incomes spent for goods and services and the marked increase in consumer willingness to take on installment debt. A parallel strengthening in business psychology was manifested in stepped-up rate of plant and equipment spending and a gradual pickup in outlays for inventory. Confidence in the economy was also reflected in the strength of the stock market and in the stability of the bond market. For the year as a whole, consumer and business sentiment benefited from rising public expectations that a resolution of the conflict in Vietnam was in prospect and that East-West tensions were easing.

The underpinnings of the business expansion were to be found in part in the stimulative monetary and fiscal policies that had been pursued. Moreover, the restoration of sounder liquidity positions and tighter management control of production efficiency had also helped lay the groundwork for a strong expansion. In addition, the economic policy moves made by the President had served to renew optimism on the business outlook while boosting hopes that inflation would be brought under more effective control.

Finally, of course, the economy was able to grow as vigorously as it did because sufficient flexibility existed in terms of idle men and machines.

The United States balance of payments deficit declined sharply. Nevertheless, by any other test, the deficit remained very large, and there was actually a substantial deterioration in our trade account to a sizable deficit, almost two thirds of which was with Japan. While the overall trade performance proved disappointing, there are still good reasons for expecting the delayed impact of devaluation to produce in time a significant strengthening in our trade picture. Given the size of the Japanese component of our trade measures undertaken by Japan. Also important will be our own efforts in the United States to fashion internal policies consistent with an improvement in our external balance.
