It was not merely that a good deal of what was said was unintelligible. The Marshall children were quite accustomed to incessant conversations between their elders of which they could gather but the vaguest glimmering. They played about, busy in their own absorbing occupations, lending an absent but not wholly unattentive ear to the gabble of their elders, full of odd and ridiculous-sounding words like Single-tax, and contrapuntal development, and root-propagation, and Benthamism, and Byzantine, and nitrogenous fertilizers, and Alexandrine, and chiaroscuro, and surviving archaisms, and diminishing utility--for to keep up such a flood-tide of talk as streamed through the Marshall house required contributions from many diverging rivers. Sylvia was entirely used to this phenomenon and, although it occasionally annoyed her that good attention was wasted on projects so much less vital than those of the children, she bore it no grudge. But on the rare occasions when Aunt Victoria was with them, there was a different and ominous note to the talk which made Sylvia acutely uneasy, although she was quite unable to follow what was said. This uncomfortable note did not at all come from mere difference of opinion, for that too was a familiar element in Sylvia's world. Indeed, it seemed to her that everybody who came to the Marshall house disagreed with everybody else about everything. The young men, students or younger professors, engaged in perpetual discussions, carried on in acrimonious tones which nevertheless seemed not in the least to impair the good feeling between them. When there was nobody else there for Father to disagree with, he disagreed with Mother, occasionally, to his great delight, rousing her from her customary self-contained economy of words to a heat as voluble as his own. Often as the two moved briskly about, preparing a meal together, they shouted out from the dining-room to the kitchen a discussion on some unintelligible topic such as the "anachronism of the competitive system," so loudly voiced and so energetically pursued that when they came to sit down to table, they would be quite red-cheeked and stirred-up, and ate their dinners with as vigorous an appetite as though they had been pursuing each other on foot instead of verbally.
