Propolis season. Normally, it is dark brown in color, but it can be found in green, red, black, and white hues, depending on the sources of resin found in the particular hive area. Honey bees are opportunists, gathering what they need from available sources, and detailed analyses show that the chemical composition of propolis varies considerably from region to region, along with the vegetation. In northern temperate climates, for example, bees collect resins from trees, such as poplars and conifers (the biological role of resin in trees is to seal wounds and defend against bacteria, fungi and insects). "Typical" northern temperate
Stitch and glue As such, unlike other construction techniques of the day, which required specialist skills and tools, Stitch and Glue was supposed to put boat-building within the reach of the average public. Although stitch and glue is similar to a traditional form of boatbuilding from northern Europe, particularly Lapland, called "sewn boats", it is not known if Littledyke's development of the stitch and glue methods was influenced by that technique. In the United States stitch and glue boat building was popularized in the mid-1980s largely through Harold "Dynamite" Payson's articles in "WoodenBoat" magazine and books on building "instant boats" designed by Phil
