"He peered sideways up and gave a long low whistle of call, then paused awhile in rapt attention . . . Two strong shrill whistles answered through the calm." What is happening here? Mulligan seems to be wryly, apishly sending a request up to God in heaven (the “old chap” of the following paragraph), and, astonishingly, receiving confirmation in the form of a quite audible reply. Has the mock mass suddenly turned seriously successful?
