Rose Hill, the residence of Thomas Page, Esq., near Waltham, a pretty country residence fast rising into repute in the horticultural world, and named in honor of the proprietor's favorite flower, which he cultivates largely and successfully, sparing no expense to obtain all the varieties worthy of cultivation. This place is situated on a gentle eminence, and commands a beautiful prospect of the picturesque scenery for many miles around. This part of the country is beautifully varied with wood and water, and admirably adapted for villas and villa gardens, and it is rather surprising that the vicinage of this pretty suburb is not more employed for that purpose by the wealthy Bostonians.

The mansion of Mr. Page is a neat and commodious structure with much interior com-fort and convenience, but it has one radical fault. It is too little and too low for such a commanding site, while the offices and outbuildings adjoining are too conspicuous. This is a very prevalent defect about the Bostonian suburban villas, and nothing is more common than to see pretty Tuscan, or Gothic, or Italian villas, with a bam standing alongside, of four times its size, out of all character and proportion. Mr. Page is fully aware of this fault, and contemplates a thorough alteration, by which this feature will be entirely done away with. Much has already been done on this bleak hill to change its original aspect, and when all the improvements now in contemplation are completed, this Will be one of the prettiest suburban villa residences in the whole neighborhood of Boston.

Among the recent improvements at Rose Hill, is the erection of a handsome green-house, with a wing attached for the purpose of growing roses alone. This is one of the prettiest green-houses about Boston; it is roomy and commodious, and we were informed by Mr. Page, it is admirably adopted to the cultivation of plants. It is heated by hot water pipes, and this winter has thoroughly tested their capacity of keeping Jack Frost at a respectful distance. This house is now quite filled with a choice collection of all the different varieties of green-house plants, including a choice collection of Camellias. We observed some fine large Azaleas in full flower, as well as Acacias also flowering splendidly. The collections of Geranium, Cineraria, Calceolaria, Primula, etc., were very fine, and some specimens exhibiting very superior skill in their cultivation. The other house was filled chiefly with roses, in good condition, though rather backward, and not producing so many blooms as we would like, but those produced were truly superb - especially the hybrid perpetuals, which Mr. Page grows largely in pots; among the rest Mr. P. showed us Fortune's five-colored rose, which, from the specimen there presented in full flower, we are very much inclined to pronounce a complete humbug.

The bud in embryo is just like a monstrosity very common in the rose family, and when fully expanded, is little else than a cluster of half developed leaves struggling for light. This is like many other much talked of floricultural and horticultural importations, which come across the channel with high sounding names, and nothing else.
