about midnight
One good arose out of this evil , however . Landing on the Bell Rock invariably cured the sickness for a time , and the sea-sick men had such an intense longing to eat of the dulse that grew there , that they were always ready and anxious to get into the boats when there was the slightest possibility of landing . Getting into the boats , by the way , in a heavy sea , when the lightship was rolling violently , was no easy matter . When the fine weather first broke up , it happened about midnight , and the change commenced with a stiff breeze from the eastward . The sea rose at once , and , long before daybreak , the Pharos was rolling heavily in the swell , and straining violently at the strong cable which held her to her moorings . About dawn Mr. Stevenson came on deck . He could not sleep , because he felt that on his shoulders rested not only the responsibility of carrying this gigantic work to a satisfactory conclusion , but also , to a large extent , the responsibility of watching over and guarding the lives of the people employed in the service .
