Hellebore grew over the swamp, and the tall grasses took on coarser forms as I waded farther on, deeper and deeper into the sphagnous grave of the ancient lake. At times it seemed so soft and spongy that I questioned my safety, even doubting the possibility of a search party securing my “embalmed heart,” if once I became fast in the mud, so I began to edge up toward firmer ground and the rocky hills near by. This was the most uncertain swamp I had ever traversed, and not quite safe for one to wade through alone. It is reputed to have been at one time the bed of a great lake, as evidenced by the terraced hillsides about it. Its waters might still linger beneath the black-peat and forest débris which support the trees and spongy sphagnum. However, a fence closed off the most dangerous parts of the bog to keep back the cows from the mire and “dead holes,” as the unfathomable places are designated by the lads who penetrate these bogs for the marsh cranberries in the autumn. I searched through this meadow for the Large Purple-Fringed Orchis (_Habenaria grandiflora_), thinking perhaps I might find the leaves, although I was somewhat too early to secure the flowers, since they are not due until June 20th and later. On striking out for the hillside path, I found many problems to solve. It appeared impossible to gain a firm or safe footing in the sphagnum and mud, so securing a fence board which had been hurled about the marsh by the winds and storms, I slapped it down upon the soft earth and moss, and walked its length of eight feet. Then quickly relaying it, while my feet sank lower and lower in the moss, I hastened to pull out my muddy foot-gear and walked the length of my bridge once more,—repeating this perilous feat several times, until I had finally crossed the “dead hole” and stood on _terra firma_ once more. There is certainly no experience like being stuck in a bog to arouse fearful forebodings. The discouraging effort to keep one foot above the ground only to find the other sinking deeper is most terrifying, and leads to hasty and excited movements which but increase the danger, and may finally lodge both feet fast in the mud. In such a case the sight of a board fence upon which an elbow may be rested is as welcome as a sail to a ship-wrecked mariner. There is in truth much art and science in walking safely through mud and sphagnum. One cannot saunter over the surface, and meditate at ease, but one must be ever alert, elastic as a rubber ball, and quick to feel a danger before it can be seen.
