On February 13, 1954 a heavy infestation of small galls was noted on a growth of willow shrubs (Salix sp.) in London Township about a mile north of London, Ontario. The exact location was on the north bank of the North Branch of the Thames River about 100 yards west of the bridge by which Adelaide Street crosses the river. The bushes were crowded along the bank and several of them had their lower branches under water and their roots extending well out into the mud of the river. The galls were one-eighth to three-eighths of an inch long (Fig. 1) and were roughly spherical to oval in shape. The bark of a gall was scarred by shallow furrows running along its length. At its upper end each gall bore the scales of a withered bud or an oval scar from which the scales had fallen. Flanking the scar were two rounded swellings of incipient buds. Many of the galls were separatelv developed along the twigs, being well apart from one another, hut in some cases they were crowded against one another so that three or four galls occupied one inch of the length of the twig, and in several instances a number of adjacent galls had coalesced to form an irregular swelling one or two inches long, along the length of a twig. In the key to insect galls of willow in Felt (1940) the galls were identified as scarred willow galls caused by the gall fly Phytophaga tumidosae (Felt).

In recent years, the attention of some archaeologists has been directed to the Canadian Northwest with the expectation of finding some evidence or indication of the early migrations of man on this continent. That man reached North America by Bering Strait from Asia, is generally accepted, but the theory that the migrations took place in late Pleistocene times and by way of an open corridor between the Keewatin ice and the Rockies, requires confirmation. It is significant that Folsom and Yuma points from Saskatchewan, described by E. B. Howard, were found mainly in areas bordering the ancient glacial Lake Regina.As a further contribution to this problem, it seems desirable to present a brief description of a carved stone relic found in gravel in central Saskatchewan about three years ago.The stone was found about seven miles southeast of the town of D'Arcy in a gravel pit located on Sec. 9, Tp. 28, Rge. 18, W. 3rd Meridian, on the north bank of a ravine running east into Bad Lake.

Opening ParagraphAccording to a partial census taken in 1960, Bamako city has about 130,000 inhabitants. Small by Western standards, it is still by far the largest city in Mali. At the time of the French conquest Bamako had only between 800 and 1,000 inhabitants; it was the capital of a Bambara chiefdom, grouping about thirty villages on the north bank of the Niger river, with a total of about 5,000 people. The ruling dynasty was that of the Niaré, who, according to their traditions, came from the Kingi eleven generations ago (between 1640 and 1700). For defence against the neighbours and armed slave-raiders fortifications were built around the town and a permanent army of so-fa (horsemen) was raised. Soon after its foundation Bamako attracted Moslem Moors from Twat who settled as marabouts and merchants under the protection of the Niaré's warriors. Among them, the Twati (later to be called Touré) and the Dravé became, alongside and sometimes in competition with the Niaré, the leading families.

This is a brief report on an archeological survey of James Bayou in East Texas that was organized to find the site of a large Historic Caddo Indian village that was reported to be in the area. Much is known about the village people. They were Kadohadacho Caddo from the Great Bend region of the Red River in Southwest Arkansas who had migrated to the area now known as James Bayou about 1800. The population of the village they established was reported to be near 500 people, and they stayed in the East Texas and Northwest Louisiana area into the early 1840s. However, none of the early contemporary writers who provide this information reported the exact location of the village, and thus the site's location was unknown when the survey was initiated. As of this report, we have surveyed both sides of James Bayou from the Louisiana line to near Stratford Lake. This was our target area since the lower Louisiana part of the Bayou had been surveyed in 1986-1987 under my direction by Shreveport members of the Louisiana Archaeological Society. In all of this vast area the only sites found on both surveys old enough to be components of the Caddo village were in a four mile area along the 200-250 foot contour on the north and east sides of James Bayou. The ten sites found and tested seemed to have a date range of 1790 to, the 1840s, which is the same as the occupation range of the Caddo village. These sites could well be components of the village since no records that we can find report anyone else in that part of Spanish East Texas through the entire period.

SummaryExcavations in 1969 within a 35-acre enclosure at Marden on the north bank of the River Avon in the Vale of Pewsey confirmed its association with the Grooved Ware ceramic style and its superficial resemblances to the Durrington Walls enclosure ten miles downstream. A survey of the enclosure produced an unusual plan bounded by a bank with an internal ditch and on the south side by the River Avon itself, whilst the position of the Hatfield Barrow was established by geophysical means. Within the north-entrance causeway a small circular timber structure was recorded in a comparable position to the much larger building at Durrington Walls.

The archaeology of the first permanent settlement of London is described. New roads were laid out c. AD 48 leading to a site that may have served as a supply-base on the north bank of the Thames. This was set out following a grid-plan around a central area where the forum was later established. Various features illustrate the importance of the managed traffic of military supplies. The topographic, ritual, and political importance of the Thames crossing at London Bridge is stressed, and the evidence of foundation burials and deposits associated with the early layout of the settlement summarized.

The Barguzin River flows out of the Barguzin Mountains, through the town of Barguzin and then the coastal community of Ust-Barguzin before it finally loses itself in a broad cove of Baikal known as Barguzin Bay. The only way across the river for miles upstream from the lake is a ramshackle little wooden ferry with a tiny, corrugated steel shed with a wood stove in it and room on its deck for about half a dozen cars. The ferry slips noiselessly away from the end of the road on the south bank, and looking west toward the lake, two ghostly, rusting timber loading cranes loom on the horizon while the river spills over into a grassy marsh on its north bank. Turning back to the east, there’s a small motorboat laboring to get upstream—laboring because it’s attached to a tow rope, which is attached to the ferry. The ferry, it turns out, is just a hapless little barge, at the mercy of the river without the guidance of the motorboat pilot on the other end of the towline. Our crossing takes less than five minutes, and connected to it by nothing but that single strand, the pilot directs the barge into place perfectly on the far side. But the deckhand fails to secure it, the ferry swings wide in the current, spins ninety degrees, and slams butt-end into the dock. The pilot scowls as he turns the motorboat around and uses its blunt bow, covered in a tractor tire, to push the barge back into place, where the deckhand finally lashes it to the dock. The Barguzin is Baikal’s third largest tributary, after the Selenga to the south of here and the Upper Angara to the north. It carries about six percent of the water flowing into the lake, along with migratory fish like omul and sturgeon, born in the shallow gravel beds upriver before wandering downstream to spend most of their lives in the lake. And even though it flows through only two towns between its headwaters and the lake, the Barguzin carries a significant pollution load into Baikal, as well, especially organic chemicals from timber operations.

It has often occurred to me during my Alpine wanderings that masses of earthy material containing boulders are too readily identified as moraines. That the latter exist, both here and in other mountain regions, no one would for a moment dispute, but deposits, sometimes very closely resembling till, may be produced in other ways. One is by a bergfall. The result of this in some cases, as at Goldau, Plurs, near San Vito (Ampezzo road), or the Col de Cheville, can be easily recognized; but when the fallen material consists largely of shale and friable rock, when there is a certain admixture of boulders from a distance (formerly perched blocks), its origin is not so readily determined. The enormous mass of débris on the north bank of the Rheinthal, between Chur and Ilanz—a mass which extends from Digg, through Flims, to rather beyond Laax, consisting of earthy stuff, probably mainly smashed shale or slate, and of boulders, apparently limestone—is regarded as bergfall by the Swiss geologists, and yet any section in it might readily be taken for moraine. Even more moraine-like in general aspect are the singular mounds of débris in the valley of the Rhone near Sierre.

At sunrise on 14 July 1586, the only three Jesuits then in England, William Weston, Henry Garnet and Robert Southwell, rode westwards out of London. They were making for Harleyford, a mansion on the north bank of the Thames, two miles upstream from Marlow and backed by the beechwoods of the Chilterns. There they lay hidden for a week, ‘discussing', as Weston cautiously wrote, ‘our future methods of work and the prospects that lay before us'. The owner of Harleyford, Robert Bold, was a keen musician, and in the mornings Mass was sung with a mixed choir, organ and other instruments, conducted by no less a master than William Byrd. Perhaps one or more of Byrd's own settings, especially the bare and haunting Mass for Three Voices, was first performed during this octave. Nearly the whole of the morning, says Weston, was taken up by Mass, preaching and confessions.
