_Vegetables._ Watering gives vegetables long exposed a fresher colour, and a more attractive appearance; but repeated waterings are highly pernicious, as they neutralize the natural juices of some, render others bitter, and make all others vapid or disagreeable.--_Ibid._ _Mortar._ The use of lime in mortar, is to fill up the hollow spaces or vacuities between the grains of sand, and to cement them together, thereby forming a kind of artificial stone. To add any more lime than is sufficient to fill up these spaces, seems to be useless, and to add much more must weaken the mortar; but, if too little lime be used, there will be cavities left between some of the grains of sand, and the mortar will consequently be short or brittle: therefore, when we cannot ascertain the best proportions of lime and sand, it is better to use too much lime than too little.--_Ibid._ _Treatment of Gold and Silver Fish._ These beautiful objects of the animal kingdom, though long ago introduced into Europe from China, their native country, seldom breed in such numbers as they might be expected to do. It has been lately discovered that in ponds heated by waste water discharged from steam factories, the gold and silver fish breed abundantly. From this circumstance, it has been suggested, that, as heating hothouses by warm water is now so generally adopted, a portion of this, led occasionally into a garden basin, would keep the water in such a temperament as would not only always be agreeable to the fish, but promote their breeding.--_Ibid._ _Climate._
