Among shrubs employed in the embellishment of ornamental grounds, there are a certain number which recommend themselves under nearly all circumstances; or, as pomologists say of fruits, "worthy of general cultivation." To aid those who desire to make small collections, and who prefer real excellence to rarity or novelty, we subjoin a short list that we can cordially recommend. We may remark, however, that in making such selections, it is desirable to obtain variety as far as it may be possible to combine it with other requisites. We do not mean the greatest possible number of genera, or species, or varieties, but various habits of growth, foliage, flowers, fruit, seasons of blossoming, and such other characteristics as are generally sought and prized in ornamental shrubs. The following list includes nothing but what is perfectly hardy in the climate of Rochester, (latitude 43 deg.,) and of easy cultivation, requiring no nicety in soil, situation, or treatment:

1. The Pink Mezereon - Daphne Mzereon

The Japan Quince - Pyrus Japonica

A prickly, spreading bush, covered in early spring (April) with bright scarlet flowers. One of the most attractive of all spring-flowering shrubs.
