Not more than two hundred yards from the wood, a ridge sank and allowed the surplus water from one flattened area of grassy marsh to drain through to the next. On the north side of the trickle the ground rose slowly to the full height of the ridge again, perhaps a yard above the marsh-level. Midway up the little slope, on a dry bit of ground, a few stalks of scrub-birch partially shielded the jack snipe from view as it sat on the nest by the side of a cloudberry plant. Not that shelter was needed. The nest would never have been found had my foot not happened to drop within a few inches of it. Then away the bird flew, with a low, almost direct flight, without any sudden twists for some twenty yards, then down into the marsh. When flushed it disappeared from view into the marsh and was not seen again until within a few feet of the nest. Once, when spotted a couple of yards away, it covered that short distance a foot at a time, crouching down for a few seconds between each very short journey; then, still crouching, it covered the eggs and remained motionless. The nest was found on June 12th, 1926, and it then contained four eggs. The last time I inspected it was on July 6th, when the eggs were cracking at their larger ends. _Eggs._--The eggs are extraordinarily large for the size of the bird, being but little smaller than those of the common snipe (_Capella gallinago_). They are, as a rule, more or less distinctly pyriform and are normally four in number. The ordinary types vary in ground color from "chamois" to "cream buff" in the buff types and "olive-lake" or "corn-olive" to "olive-buff" in the green types. As a rule, the markings are somewhat smaller and more uniformly distributed than in common snipes' eggs. They are in some shade of light or dark brown, such as "tawny," "russet-vinaceous," "chocolate," "liver," or "chestnut brown"; the underlying markings, which are numerous and conspicuous in some cases, are in various shades of "purple drab" or "drab-grey." The spiral smears, so frequently found in common snipes' eggs, seem to be absent from those of the jack snipe, and, though there are some cases of wide variation in coloring, a series will be found to be browner and less bold in markings than a corresponding number of the common species. The measurements of 146 eggs average 38.53 by 27.37 millimeters; the eggs showing the four extremes measure =44.5= by 28.5, 40 by =30=, =35= by 27 and 38 by =25.5= millimeters. Rey (1905) states that the shells are somewhat thinner and lighter than with the common snipe and gives the average weight as 660 grams. _Plumages._--The downy plumage is described by Dresser (1871) as follows, from a nestling obtained at Muonioniska:
