Dr. James Fergusson, in an appendix to his work on "Rude Stone Monuments of All Countries," gives, at length, an account of the opening, in 1846, of a huge tumulus, named "Oden's Howe," near Upsala, by Herr Hildebrand, the royal antiquary of Sweden. The similarity of many of the remains brought to light to those found in the "Castle Hill," seems to suggest that these tumuli were erected by cognate people, and at no very distant periods from each other. Herr Hildebrand says,--"During the diggings were found unburnt animal bones, bits of dark wood, charcoal, bits of burnt bones, etc. This was evidently a sepulchral mound. Diggings have also been made in the smaller cairns near by, and, although they have been opened before, burial urns have been found, burnt human bones, bones of animals and birds, bits of iron and bronze, etc.... At the middle of the howe, the grave-chamber is nine feet above the level of the soil, 18 feet under the top of the howe. On the bed of the clay, under the great stones, have been found an iron clinker three inches long, remains of pine poles partly burnt, a lock of hair chestnut coloured, etc. The numerous clusters of charcoal show that the dead had been burned on the layer of clay, and the bones have been collected in an urn not yet found. In one of the nearest small howes have been found a quantity of burnt animal and human bones, two little-injured bronze brooches, a fragment of a golden ornament, etc." After further examination of the contents of the howe, Herr Hildebrand says, "June 29th, 1847,--The burial urn has been found in the grave-chamber, also have turned up bones of men, horses, dogs, a golden ornament delicately worked, a bone comb, bone buttons, etc." He afterwards writes to say that the burial urn was found three inches under the soil, and was covered with a thin slab. "It was seven inches high, nine inches in diameter, filled with burnt bones, human and animal (horse, dog, etc.), ashes, charcoal (of needle and leaf trees), nails, copper ornaments, bone articles, a bird of bone, etc. In the mass of charcoal also were found bones, broken ornaments, bits of two golden bracteates, etc. Coins of King Oscar were then placed in the urn, and everything restored as before. Frey's Howe was opened, and showed the same results." "Dr. Fergusson, commenting on this, says--"With a little local industry, I have very little doubt, not only that the date of these tombs could be ascertained, but the names of the royal personages who were therein buried, probably in the sixth or seventh century of our era."
