In June, 1780, a new “petite rivière” was planned to receive the water drained from the “ravin de la grotte,” and to conduct it into the larger lake. For this purpose a new grotto was made of a “forme ovale, ornée en glaçon,” through which the “petite rivière” was to run. A “ravin du petit pont” was also planned.[[36]]

In August, 1780, masses of rock were procured, and the “petite rivière” was begun, and also a hill was thrown up “pour couvrir la grotte.”[[37]]

In September, 1780, “Bourdin a passé la journée ... à poser le deuxième pont venant du coté de la grotte.”[[38]] This second bridge was probably the present Rocher bridge, being the second placed over the lakes. Neither of these two bridges would be the “pont de bois,”[[39]] and “la conduitte en bois,”[[40]] two descriptions of, and identical with, the one alluded to in the words “ravin du petit pont,” which was said to have been erected on high ground “au dessus du Rocher du Ravin.”[[41]]

In December, 1780, the work was finished: “Conduitte de l’exécution de la grotte, petite rivière, et chutte d’eau retombante dans le grand lac, autre petits ravins dans la montagne près du grand lac à la fin de la petite rivière de la grotte.”[[42]]

In 1781 a “montagne” was made “en face du jardin français—en face de la comédie.”[[43]]

In March and April, 1781, a hill called “l’Escargot” was piled up[[44]]—beyond the Belvédère—and, presumably, a third and very small grotto was made. The creation of the Escargot hill would have made the “ravin” on the north side of the Belvédère, which is still visible, and leads to the greater lake.

There are several reasons why we think that the Queen’s grotto (the second made) was on the theatre side of the Belvédère.

1. D’Hezecques’ description of it in 1789 shows that, though a “ruisseau” passed through it, persons could go freely out at both ends;[[45]] whereas when water was passing down through the upper entrance of the “escargot” grotto, no one could have used it at the same time: there is only room for the water.

2. He speaks of the “prairie” being visible from “une crevasse, qui s’ouvrait à la tête du lit”; this would have been possible from a grotto on the theatre side, but not on the other, as the “escargot” hill would have been in the way.
