Every body fond of flowers knows that there is nothing in the " wide" floral " world" comparable for refined beauty and loveliness to a fine tea rose, in fact to tea-roses altogether. South -of Pennsylvania, they are grown as easily as common garden roses, bearing all ordinary winters witkimpunity. But north of Philadelphia, the tea-rose is too tender to grow all the year round out of doors - and is therefore for the most part confined to the green-house or frame.

A little experiment that we made last winter, with a bed of tea-roses, containing a couple of dozen plants, has turned out so entirely to our satisfaction, that we think it removes all the difficulty of making permanent beds of tea-roses at the north. The temperature having been so unusually severe, and the plants only one season planted, the result is all the more satisfactory. We make the process known for the benefit of floral devotees.

The bed was oval. We covered it early in November with tan-bark, one foot thick - which nearly covered all the stems - the longest being bent down. Over this coat of tan, to keep it dry, (that being the main point,) we put three bundles of rye-straw - gathering it in the center to a ridge or point - so as to shed off the water entirely; no further attention was paid it. When the straw was removed in April, the tan was found perfectly dry - on removing the tan the plants were found in perfect order - even the leaves of the last autumn's growth as fresh as when covered. If any of our readers can invent a simpler or more effectual mode of preserving a bed of tender plants, we should like to hear from them.
