AFRICAN GABIONS RECENTLY CELEBRATED ten
years of partnership with Maluti Irrigation, the
company's distributor in Lesotho.
On the occasion, Gary Matthews, regional
manager of African Gabions in Johannesburg, said:
'Maluti Irrigation and African Gabions have in the
past decade substantially increased the awareness
of the soil erosion needs in Lesotho. Lesotho might
be a small country, but the consequences of soil
erosion are huge and affect not only the Kingdom
of the Mountains, but South Africa as well. We are
proud to have been associated with Terry Fraenkel
and his Maluti Irrigation team, and to have ..

BAIN'S KLOOF PASS: GATEWAY TO THE NORTH, BY
SANDRA STEYTLER AND HANS NIEUWMEYER.
PUBLISHED BY THE AUTHORS IN ASSOCIATION
WITH MARTIN WELLS OF SUMMIT PUBLISHING,
CAPE TOWN, 2003
THE AUTHORS HAVE PACKED a lot of careful research into
70 A5 pages. Both Mountain Club members, they were for
twenty years responsible for the club's property in Bain's
Kloof and travelled through the pass on an almost weekly
basis. Their passion for the pass permeates the book. More
than that, it drives it right from the very first words: 'We
have watched with consternation the environmental deterioration'

building in Thornhill Office Park,
Preparations are well under way to
move in by the end of March 2005.
This facility is modest but smart and
will serve SAICE members and their activities
well into the future. Our call on
members to contribute to reduce the outstanding
bond has resulted in a small but
well-appreciated beginning. A number of
our technical divisions and branches
have resolved to invest in the building
and we also have received a couple of
pledges for donations from them.

This paper concerns the performance of a 24000 lb pentagon shaped prototype compactor. This machine imparts a series of impacts due to its mass dropping about 8 in. onto an area of about 8 square feet. Steady rolling action is achieved by springs and damping devices in the towing mechanism. At a recent trial, surface settlement, sub-surface settlement, penetrometer and density observations, together with pressure cell measurements, showed that the pentagon compactor achieved an appreciably better effect than other rollers and, with a higher work output, should prove to be economical. It is suggested that the pentagon compactor offers an alternative to heavy pneumatic rollers for proof of subgrades and should prove useful for compaction of mixed soil and rocks and landfill rubbish dumps as well as for deep compaction soils in general.
The paper descriptionbed the mechanics of landslides and identified their cause. The strength properties of the stiff fissured clay at Amsterdamhoek and the weathered felspathic sandstone at Bethlehem were descriptionbed and strengths measured in small-scale tests were compared with the strength of the soil in bulk. It was concluded that both the short- and long-ter stability of slopes in stiff fissured materials is governed by the shearing resistance along fissures in the soil.
The original paper, which was published in the October 1970 issue of the Transactions, was written by L. T. Campbell Pitt. It was presented with the object of initiating discussion leading to the formulation of a policy by the Federation of Societies of Professional Engineers on the training of technicians.
Methods are presented for the calculation of wind loads on tall structures. The 'static' case, where wind loads are taken as acting steadily, is considered briefly. Dynamic effects, which arise on elastic structures due to loads varying with time as a result of wind gusting and vortex shedding, are dealt with more fully. So-called 'galloping' oscillations are also considered briefly.
