Lieutenant Beachey, in his _Travels in Cyrene_, recently published, has thrown some curious light on the ancient account of these celebrated gardens. It appears, that, like many other wonders, ancient and modern, when reduced to simple truth, they are little more than common occurrences. Baron Humboldt and Mr. Bullock have reduced the floating gardens of Mexico to mud banks, with ditches between; and lieutenant Beachey makes it appear, that the gardens of the Hesperides are nothing more than old stone quarries, the bottoms of which have been cultivated. _Preparation of Cinnamon_. The rough bark is first scraped off with knives, and then, with a peculiar instrument, the inner rind is stripped off in long slips; these are tied up in bundles, and put to dry in the sun, and the wood is sold for fuel. The operation was thus explained to bishop Heber by the cinnamon peelers; but in the regular preparation, the outer bark is not scraped off; but the process of fermentation, which the strips undergo when tied up in large quantities, removes the coarse parts. The peelers are called Chaliers. _Power of the Sun's Rays_. Mr. Mackintosh, contractor for the government works at Stonehouse Point, Devon, lately had to descend in the diving-bell with workmen to lay the foundation of a sea wall. The machine is fitted with convex glasses, in the upper part, to serve the purpose of windows; and Mr. Mackintosh states, that on several occasions, in clear weather, he has witnessed the sun's rays so concentrated by the circular windows, as to burn the labourers' clothes, when opposed to the focal point, and this when the machine was twenty-five feet under the surface of the water!--_From the MS. Journal of the Bristol Nursery Library_. _The Cowslip and Polyanthus_. By sowing the seed of the wild cowslip in the garden, a number of varieties will be produced, some of which have flowers of a beautiful bright red colour. May not this process be the first step towards the formation of our garden polyanthus? if that be not, as is generally supposed, a variety of the primrose, rather than of the cowslip.--_Gard.
