The first time we saw Irish Yews used for this purpose the effect was very much admired, being studded all over with its reddish fruit, thus greatly relieving its somewhat sombre appearance. The Irish Yew has a very pretty appearance, if a good healthy plant, growing in good soil and well drained, when managed well from first planting. On laying every plant off regularly into its proper position, and trimming off every superfluous shoot, there should not be the least overcrowding of the branches at any place, more than is necessary to give proper effect. To those who may not have seen Irish Yews used for this purpose, I would say, give them a fair trial before forming an opinion of their merits.
