A person carrying some orange trees from China to the Prince of Wales' Island, when they had many hundred fruit on them, expected a good crop the next year, but was utterly disappointed: they produced but few. A Chinese, settled in in the island, told him if he would have his trees bear, he must treat them as they were accustomed to in China; and he described the following process for providing manure:

" A cistern, so lined and covered as to be air-tight, is half-filled with animal matter; and to prevent bursting from the generation of air, a valve is fixed which gives way with some difficulty, and lets no more gas escape than is necessary: the longer the manure is kept the better, till four years, when it is in perfection; it is taken out in the consistence nearly of jelly, and a small portion buried at the root of every orange treethe result being an uncommonly great yield." A person hearing of the above mot, and wishing to abridge the term of the preparation, thought that boiling animals to a jelly might have a similar if not so strong an effect. Accordingly, he boiled several puppies, and applied the jelly to the roots of a sterile fig-tree: the benefit was very great - the tree from that time for several years bearing in profusion Hints of this kind are well worth preserving, for though a farmer may neither have the apparatus of the Chinese, nor puppies enough to become an object of attention, yet the reduction of manure to a mucilaginous state ought perhaps to be carried further than it is.
