The old advertisements to which we have referred are very interesting to look back upon, and afford material for a history of horticulture quite invaluable. Fortunate are those who, in binding their copies, have not destroyed the advertisement sheets. We can only allude to a few samples to confirm our statement. The very first advertisement is one by T. Rivers, jun., of a new perpetual Rose called Prince Albert, described as a cross raised by M. Laffay, of Paris, from the Bourbon Gloire de Rosamene, fertilised with the pollen of some Damask and hybrid China Roses [sic]! Plants at a guinea each were announced to be delivered to subscribers at Mr. Kernan's, 4, Great Russell Street, Covent Garden. The name of Rivers is still in the fore front, and many of our older readers will remember Kernan, but the Rose—where is it?

Historique de la Culture du Rosier.
C'est à M. Laffay que revient l'honneur d'avoir créé la magnifique race hybride remontante: les premières variétés, le prince-albert et la princesse-hélène, furent obtenues par lui en 1837, mais son triomphe fut la superbe rose la reine, gain de 1843. Citons encore les roses gracieuses duchesse-de-sutherland, auguste-mie, madame-laffay. (Cet habile rosiériste habite maintenant l'Algérie.)
