The Gardener"s (LondQn) Chroaiclo Mys: m "The systcm of stripping the bark off the trunks of trees, tbr the purpqse of destroying the inseets wbicb infest tíiera, has üow been generalij applied t.o a large nuniber in th Champa Elysees, and elsewhere in Paris, and has led to the discovery of a curious but important fact. It appears tliat trees may be deprived of the Tvholc of their bark, not only witlout experieiiv-ing any injury, but even wilh considerable advantage, the operatioa in toniing to inerease thoir power of vegetation. Elms, whieh, before the opcration, did not mcreaee more than oue or two millinietres in diameter in Bach year, have been found to increase fuur or Svc when stripped of tUair bark. Trees having a very thin Tiark, such as the birch and others, need not be stripped to obtain a similar result; it is sufficient for the purpose to make longitudinal iucisions in the bark by means ota kind of three-bladed scarificator. It is now intended to subject all the young elma in a languishing state to this treatment throughont riris, it having answercd perfectly vfith thoso planted ou the fortiücations. It has long boen the praetiee uherc trees liave been denuded of their bark by cattle, to coat tbom over with some kind of couiposition, and in most cases tbc rcsult lias been bigbly satisfactory' This, of course, niust mean, not the removal of the entirc bark to tbc wood of the trunk, but tlie outside rougb bark, leaving tlio imdcr entiele unbroken. Ás the Bnp of trees flows betiveen the outcr bark aud the wood of tlio trunk, the removal of the entire bnrk would bc fatal to thcir life.
