He tried to return to his work, but found himself once more possessed by the demon of unrest and impatience. The spiritual wave that had been lifting him higher and higher was changing its character and becoming a smoothly gliding current. It was so irresistible that he never thought of resisting. "Why should he resist?" he asked himself. Circumstances had interested him in this rare Undine before she received a woman's soul; circumstances had entangled his life and hers in what had almost been an awful tragedy; and now circumstances, or something far beyond, were swiftly developing before his eyes a spiritual loveliness that was the counterpart of her outward beauty, and he assured himself that it would be the greatest folly of his life to lose a trace of the exquisite process that he might be privileged to see. What artist or poet has not pictured himself the fair face of Eve as God first breathed into her perfect clay the breath of life, or has not, in imagination, seen the closed eyes opening in surprise and intelligence or kindling with the light of love? And yet the change in Ida Mayhew seemed to Van Berg far more wonderful and interesting; and to his fancy if, instead of lying in the beauty of her breathless, statuesque preparation for life, Eve had been possessed by a legion of distorting imps, she would have been the type of the maiden he first had recognized. But he had seen these evil spirits exorcised, and in their place was coming a noble, womanly soul--sweet, tender, and strong--and the perfect form and features seemed but a transparent mould, a crystal vase into which heaven was pouring a new and divine life. Why should he not long to escape from the dusty matter-of-fact world and witness this spiritual repetition of the most beautiful story of the past? Thus his philosophical mind was able once more to reason the whole matter out clearly and prove that his wish to annihilate the intervening hours before he could dare to present himself to Ida Mayhew, was the most natural and proper desire imaginable. He concluded that a walk through Central Park might banish his disquietude, and leave time for a careful toilet, since for some occult reason the occasion seemed to him to require unusual preparation.
