“Yes, I am eager about it now,” at last exclaimed Grandidier in an animated way. “I allowed you to prosecute your experiments without troubling you with any inquisitive questions. But a solution is becoming imperative.”

Thomas smiled: “Well, you must remain patient just a little longer,” said he; “I believe that I am on the right road.”

Then Grandidier shook hands with him and Pierre, and went off to make his usual round through his busy, bustling works, whilst near at hand, awaiting his return, stood the closed pavilion, where every evening he was fated to relapse into endless, incurable anguish.

The daylight was already waning when Pierre and Thomas, after re-ascending the height of Montmartre, walked towards the large work-shop which Jahan, the sculptor, had set up among the many sheds whose erection had been necessitated by the building of the Sacred Heart. There was here a stretch of ground littered with materials, an extraordinary chaos of building stone, beams and machinery; and pending the time when an army of navvies would come to set the whole place in order, one could see gaping trenches, rough flights of descending steps and fences, imperfectly closing doorways which conducted to the substructures of the basilica.

Halting in front of Jahan’s work-shop, Thomas pointed to one of these doorways by which one could reach the foundation works. “Have you never had an idea of visiting the foundations?” he inquired of Pierre. “There’s quite a city down there on which millions of money have been spent. They could only find firm soil at the very base of the height, and they had to excavate more than eighty shafts, fill them with concrete, and then rear their church on all those subterranean columns.... Yes, that is so. Of course the columns cannot be seen, but it is they who hold that insulting edifice aloft, right over Paris!”

Having drawn near to the fence, Pierre was looking at an open doorway beyond it, a sort of dark landing whence steps descended as if into the bowels of the earth. And he thought of those invisible columns of concrete, and of all the stubborn energy and desire for domination which had set and kept the edifice erect.

Thomas was at last obliged to call him. “Let us make haste,” said he, “the twilight will soon be here. We shan’t be able to see much.”

They had arranged to meet Antoine at Jahan’s, as the sculptor wished to show them a new model he had prepared. When they entered the work-shop they found the two assistants still working at the colossal angel which had been ordered for the basilica. Standing on a scaffolding they were rough-hewing its symmetrical wings, whilst Jahan, seated on a low chair, with his sleeves rolled up to his elbows, and his hands soiled with clay, was contemplating a figure some three feet high on which he had just been working.

“Ah! it’s you,” he exclaimed. “Antoine has been waiting more than half an hour for you. He’s gone outside with Lise to see the sun set over Paris, I think. But they will soon be back.”

Then he relapsed into silence, with his eyes fixed on his work.
