In 1974 Abdul Hamid M. el Zein published The Sacred Meadows: A Structural Analysis of Religious Symbolism in an East African Town. The town in question was Lamu on an island of the same name off the northern coast of Kenya. The population of Lamu, holding steady at about 5,000 during this century, is mostly Muslim and mostly of mixed Arab and African descent. Arabs began to visit Lamu centuries ago and over time Arab traders settled on the tiny island, married local women, and created what we know today in the larger context along the East African coast as Swahili language and culture. Dhows came each year with the northeast monsoon bringing Arab sailors and a trickle of new immigrants from Arabia. (Not only Arabia, however, as dhows came from many parts of the Indian Ocean to Lamu and the east coast of Africa). As sailors, Lamu people continued to revisit Arabia, among many ports, for commerce as well as for pilgrimage to Mecca. The Arab strain in Lamu culture was therefore reinforced; that culture has therefore tended to sway toward the Indian Ocean in recent centuries and to Arabia in the past one hundred and fifty years.Until the last decade or so the town had a tight social hierarchy with the old Arab (as they identified themselves) families at the top, followed by Indian traders and merchants (who often worked in partnership with the old families), and then other merchants, such as late nineteenth century arrivals from the Hadramawt, free Africans and Bajuni (the Swahili people from nearby islands), and finally, slaves (or ex-slaves after 1907).

Spirillum serpens possesses a surface layer protein which exhibits a regular hexagonal packing of the morphological subunits. A morphological model of the structure of the protein has been proposed at a resolution of about 25 Å, in which the morphological unit might be described as having the appearance of a flared-out, hollow cylinder with six ÅspokesÅ at the flared end. In order to understand the detailed association of the macromolecules, it is necessary to do a high resolution structural analysis. Large, single layered arrays of the surface layer protein have been obtained for this purpose by means of extensive heating in high CaCl2, a procedure derived from that of Buckmire and Murray. Low dose, low temperature electron microscopy has been applied to the large arrays.As a first step, the samples were negatively stained with neutralized phosphotungstic acid, and the specimens were imaged at 40,000 magnification by use of a high resolution cold stage on a JE0L 100B. Low dose images were recorded with exposures of 7-9 electrons/Å2. The micrographs obtained (Fig. 1) were examined by use of optical diffraction (Fig. 2) to tell what areas were especially well ordered.

While DNA-dependent RNA polymerase represents one of the key enzymes involved in transcription and ultimately in gene expression in procaryotic and eucaryotic cells, little progress has been made towards elucidation of its 3-D structure at the molecular level over the past few years. This is mainly because to date no 3-D crystals suitable for X-ray diffraction analysis have been obtained with this rather large (MW ~500 kd) multi-subunit (α2ββ'ζ). As an alternative, we have been trying to form ordered arrays of RNA polymerase from E. coli suitable for structural analysis in the electron microscope combined with image processing. Here we report about helical polymers induced from holoenzyme (α2ββ'ζ) at low ionic strength with 5-7 mM MnCl2 (see Fig. 1a). The presence of the ζ-subunit (MW 86 kd) is required to form these polymers, since the core enzyme (α2ββ') does fail to assemble into such structures under these conditions.
