Since my last visit to Boston, they have built a splendid building for their own use, for discussions on fruits and flowers, potatoes and cabbages, and the showing of the same on their fete days. It is a building every visitor of Boston should see. Immense halls, large library and office rooms, elegant statues, life portraits of all the presidents of the Society are among the points that attract, occupy, and invite your admiration.

From the Hall, I went to visit Hon. Marshall P. Wilder, where, as to everybody else who talks or loves horticulture, a kind welcome was extended; and after a run over the grounds, seeing the hundreds of Beurre d'Anjou and other pear trees, all evincing the care of a good husbandman, I carefully looked over large-bearing trees of Clapp's Favorite, and satisfied myself that its habit is a good one for pear-growers who do not love work, inasmuch that it is a strong grower, yet so open, and withal so erect, that little or no pruning is required.

From the garden to a look over various numbers of the Rogers' Hybrid grapes, of which I will write more some time; and then a hasty glance through the hundreds of outlines of pears, with descriptions, gathered in long years of care and attention; and then, with a look and taste of box after box, specimen on specimen of the newer and older sorts of pears, I had to come away - to come away from where, if I could stay a month, I could every day find something new to discuss, and a man to discuss it with.

From Boston to New York, where, leaving my little carpet sack, I took care to visit the Messrs. Parsons, at Flushing, where I found immense houses, filled with camellias, roses, rhododendrons, etc, and numberless houses in which grapes had been grown, but now all taken up and heeled-in, awaiting customers.

The Messrs. Parsons are very extensive growers and dealers, and especially in grapes, camellias, and rhododendrons, the latter of which I am desirous every man who pretends to have any flowering shrub in his grounds should possess. As yet, our plantations and grounds are too bare of shrub evergreens, which add cheerfulness and life without the gloomy character created by large evergreen trees.

From Flushing back to New York, where, of course, I visited the rooms of the publishers of the Horticulturist, where, although I expected to see much, I did not expect to find so much reality. The Messrs. Woodward are live men, and we who read the Horticulturist may be thankful therefor; they see and appreciate the wants of the people, and are exerting themselves to create books and illustrations to meet those wants.

From New York to Newburgh, where, of course, every pomologist knows that Charles Downing is the first man to be called on by any one who wants to talk fruit. As usual I found him busily engaged, for he is a man knowing no idle hours, with his fruits, his flowers, etc. Outlining a fruit, gathering or protecting a flower, grafting, budding, planting, pruning and training tree or vine are his occupations, and the world knows not, nor will ever appreciate the value of such a man. With some fifteen hundred or more varieties of apples, nine or ten hundred of pears, and of cherries, plums, etc, with all the smaller fruits, growing in his own grounds, it is a labor of no small amount to examine, keep distinct, classify, portray, and 'describe them all, and he only who has practised on a hundred or two can, perhaps, understand it. Without pretension, without desire for public appreciation, this man, solely from the love of the subject, is sifting the chaff of fruit and flower from the wheat, and making his record thereof; and should he ever publish, we outsiders would reap the benefit.

The Hudson River, it is well known, abounds in beautiful places, many of which I visited, but cannot now write of. However, I may mention that at Fishkill, the place of H. W. Sargent, Esq., amused while it instructed me. As a landscape place, its arrangement is anything but correct; but as a place where one may study trees, new and rare, and particularly evergreens, it is, perhaps, more valuable than any other. I may, however, say that the manner in which many of the rare evergreens are protected and shaded, by natural overshadowing trees and artificial screens, gives no actual criterion of their hardihood in exposed positions.

The most beautiful place that I saw hereabouts was a recently planted and arranged one belonging to General Howland. Good judgment has been used in the arrangement of the roads, with one exception, and especially has breadth and character been kept in the position of the groups; but in the arrangement of the trees, a few years will exhibit to all, what now only appears to the student, viz., the fact that many trees are too near the paths, and that others have centre positions when they should have outside ones. Such blunders, however, are too common, and perhaps no more apparent here than in many other places; at any rate, the place is richly worth a visit by any gentleman desirous of improving his own grounds, or by any landscape artist.

On the Newburgh side of the river, the place of Geo. Eliot, Esq., pleased me most. The house is situated about in the centre of the grounds, from which extensive views are had of the grand and beautiful river, the city of Newburgh, surrounding mountains, etc.; and immediately in front, one of the finest, though not the best kept, lawns that I ever saw. It is broken just right by groups, so that extent, and yet diversity of views are obtained; and the groups, as a whole, as well as the single trees, are most capitally arranged. In rear of the house, the hill rises gradually, and, with its planting of tall trees, gives to the place a background rarely found in our country.

Further on, at a little unpretending place, over the door of which I read "Welcome to Woodbine," owned by Mr. Burton, I saw the most beautiful views of all, both up and down the river. Very little has been done to the place, but it is susceptible of being made one of the most beautiful of the many beautiful places on the noble Hudson.

At Mr. Rogers' place, I saw a grape and plant house, planned and built by the Messrs. Woodward, of the Horticulturist, which, of all the number I saw, I liked best, mainly because of its low roof, which enables a more uniform heat to be retained, at a less expense of fuel; at the same time the bouse is so proportioned that it presents a good architectural appearance outside, not "squatty," as too many do.

The next place - but stop, guess I have written enough for this time, so will leave my farther notes for a future time, should they be wanted.
