against it. On calculating the probable expense of such an apparatus as 

 shown in Vol. VI. p. 671. fig. 130., where there are two boilers, two 

 reservoirs, and 194 ft. of pipe, to two houses connected together, and only 

 40 ft. long each, any person would say that the expense would be enor- 

 mous, and for that reason would not adopt the method at all. Now, Sir, 

 those two houses contain only or about 7600 cubic feet of air, and as 

 peach-houses require a medium heat of 55°, supposing the thermometer 

 to stand at freezing, even then one boiler, both reservoirs, and 18 ft. of 

 pipe, might be dispensed with altogether. By calculation 1 find that one 

 boiler, 3 ft. 6 in. long, 1 ft. 2 in. deep, 1 ft. 6 in. wide, and 178 ft. of 4 in, 

 pipe would be quite sufficient, even if the thermometer stood at 20°. 



Should it be wished to heat one house more than another, this wish may 

 be easily satisfied by inserting a throttle valve into one of the houses, 

 which will eifectually stop all circulation of the water, if required. Hoping 

 these friendly hints will not offend Juvenis Olitor, I am, &c. — D. D.

The Poviological Magazine, — The nurserymen are not much obliged to 

 you or Mr. Lindley for your doubts as to their sending the sorts genuine 

 to their customers ; and perhaps they are better judges than yourselves 

 what to recommend, and can safely leave it to the public to decide where 

 to give the preference, although they may not be able to discover the 

 superior merit of the following "first-rate varieties of apples for a select 

 garden :" — Juneating, Boston Russet, Franklin's Golden Pippin, Sweeny 

 Nonpareil, Eraser's Pippin, Brabant Bellefleur, Sugarloaf, Sam Young, 

 Downton Pippin, Grey F. Reinette, &c. ', hardly any of which are to be 

 found in the most respectable nurseries, where, however, such sorts as the 

 following, with many more as good, are to be had : — Red Quarrenden, St. 

 JuHen, Pomme d'Api Gros, Nonesuch, East Grinstead, Salopian Pippin, 

 HoUandbury, Margil, Wyker Pippin, Fearn's Pippin, Flower of Kent, 

 Christie's Pippin, more valuable than the Beauty of Kent ; Kirke's Lord 

 Nelson, Yorkshire Greening, much better than Northern Greening; Loan's 

 Pearmain, Rymer, Carlisle Codlin, Bringewood Pippin, Kentish Broading, 

 Kentish Fill-basket, Golden Knob, Red Astracan, Cole Apple, Red and 

 white Ingestrie, Herefordshii'e Pearmain, Devonshire Redstreak, Nonpareil 

 Russet, &c. &c. 



It seems extraordinary that the editor of the Pomological Magazine 

 should only recommend the Elton as a heart cherry, which is generally 

 thought a tender fruit, to the exclusion of the old Black heart (a hundred 

 of which will probably always be planted for one Elton), the Ox heart. 

 Bleeding heart, and Florence, &c. The lists in general are scanty and 

 meagre. The Horsforth Grape, being a shy bearer and a bad setter, and not 

 being remarkable for flavour, seems not worth recommending. The Isa- 

 bella must be a very prolific lady to bear three times in a year. Padley's 

 Pippin has been frequently described. The fruit of the Reinette Grise is 

 excellent in France, but does not arrive at the same perfection here. — A 

 Nurseryman. Feb. 18.30. 



The Pomological Magazine. — The editors of the Pomological Magazine 

 err greatly, when they say that the Newton is the best of the American 

 Spitzembergs. Besides the Newton, I know of none except the jEsopus, 

 the Pownal, the White, and the New, or Jonathan. Of these fine varieties 

 the Newton is unquestionably the poorest apple; indeed, so inferior dol 

 consider it in the scale of fine fruits, that we have never propagated it in 

 our nursery, although it is growing in my grounds. — Jesse Buel, Albany y 

 Dec. 20. 1830. 



The Monteath Pear Tree at Ormiston, — Sir, Allow me to allude to 

 Vol, VI. p. 495., in which Mr. Gorrie gives an account of a jaunt he had 

 made in the Lothians. Among other things, Mr. Gorrie mentions the 

 Monteath pear tree, in the garden at Ormiston Hall, and says, that the 

 original tree is growing, and is supposed to have stood three centuries ;
