And when an old priest, assisted by a sacristan, began the mass softly at the end of the chapter, a small organ gave the tone to the voices.

Then Durtal might well wonder, for he had never before heard a sole and only voice made up of perhaps some thirty, of a tone so strange, a superterrestrial voice, which burnt upon itself, in the air, and intertwined its soft cooings.

This bore no resemblance to the icy and obstinate lament of the Carmelites, nor was it like the unsexed tone, the child's voice, squeaking, rounded off at the end of the Franciscan nuns, but quite another thing.

At La Glacière in fact those raw voices, though softened and watered by prayers, kept somewhat of the drawling, almost vulgar, inflexion of the people from whom they came; they were greatly purified, but remained none the less human. Here the tenderness of tones was rendered angelic, that voice with no defined origin long bolted through the divine sieve, patiently modelled for the liturgical chant, caught fire as it unfolded, blazed in virginal clusters of white sound, died down, flowered out again in pale pleadings, distant, seraphic at the end of certain chants.

Thus interpreted the Mass gave a special accent to the sense of the sequences.

Standing, behind the grating, the convent answered the priest.

Durtal had then heard, after a mournful and solemn "Kyrie Eleison," sharp and almost tragic, the decided cry, so loving and so grave, of the "Gloria in Excelsis," to the true plain chant; he had listened to the Credo, slow and bare, solemn and pensive, and he was able to affirm that these chants were totally different from those which were sung everywhere in the churches. St. Severin and St. Sulpice now seemed to him profane; in the place of their gentle warmth, their curls and their fringes, the angles of their polished melodies, their modern endings, their incoherent accompaniments arranged for the organ, he found himself in the presence of a chant, thin, sharp and nervous, like the work of an early master, and saw the ascetic severity of its lines, its sonorous colouring, the brightness of its metal hammered out with the rude yet charming art of Gothic jewels, he heard under the woven robe of sound, the beating of a simple heart, the ingenuous love of ages, and he noticed that curious shade in Benedictine music; it ended all cries of adoration, all tender cooings in a timid murmur, cut short, as though shrinking in humility, effacing itself modestly as though asking pardon of God for daring to love Him.

"Ah, you were very right to send me there," said Durtal to the abbé when next he saw him.

"I had no choice," answered the priest, smiling, "for the plain chant is respected only in convents under the Benedictine rule. That grand Order has restored it. Dom Pothier has done for it what Dom Guéranger has done for the liturgy.

"Moreover, beyond the authenticity of the vocal text, and the manner of rendering it, there are still two essential conditions for restoring the special life of these melodies, and they are hardly found except in cloisters, first Faith, and next the understanding the meaning of the words sung."
