With respect to the Rose Augusta, although not so deep in color as I hoped and wished for, still I will honestly confess that I have been pleased with it It differs from Salfatare in having leaves narrower and more pointed, and its flowers are decidedly of a finer shape than those of that variety, and deeper in color in the center. The flowers of Solfatare are much refiexed and flat in hot weather, which is its great fault Those of Augusta are (as it has bloomed here) incurved, and more inclined to be globular in shape. It is in my opinion a step in the right direction: but I hope it will soon be improved, for in your Northern States it might be crossed with the bright yellow, but flaccid-petalled Rose, Vicomtesse Decases, and something much more decided in color be produced. Over propagation, change of climate (in your different States remarkable), and the weather of peculiar seasons, have much effect on the color of Roses, more particularly on those of the Tea-scented and Noisette class. The first two seasons after I introduced the Cloth of Gold Rose from Angers, it bloomed in England, to my great vexation, of a dirty white.

I could scarcely believe that it was the same Rose I had seen at Angers, and I made a journey to that place expressly to have another look at it On again seeing it, I felt assured that all would be right in the end; so that I dare say when the Augasta Rose is well established it will show more its proper character.

The distinctness of the Augusta Rose having been questioned by many cultivators in this country, we requested Mr. Rivers to give us his opinion on the subject, and he has given it as above.
