than the open air, and could be roofed with thatch of maize or long grass ; or, 

 if time be allowed, vines or broad-leaved creepers would soon form a natural 

 covering. These open rooms are very frequent in Sicily, and are the most 

 delightful drawingrooms in a warm climate that can be imagined. One of tiie 

 sitting-rooms should have a small fire-place (slate stove), in case of a few cold 

 nights in winter ; for, so much is the constitution affected by a change of 

 climate, that I have often shivered with cold in the tropics, and ordered a fire 

 when the thermometer was at 68°. Economy, in a country where labour is 

 so dear, must be the first consideration with the majority. I should therefore 

 recommend all the rooms to be on the ground floor, but the walls to be so 

 contrived as to be capable, in some instances, if necessary, of being raised 

 hereafter; or the ceiling made sufficiently firm to admit of a loft between that 

 and the roof. I have a great predilection for mud walls, knowing, from expe- 

 rience, how remarkably cool they are in summer. The material is always on 

 the spot ; the erection is cheap ; and, if the cottage is coloured, and built in 

 good style, it will always be a pretty, if not a beautiful, object. Lastly, over- 

 hung roofs, or projecting additions thereto, are great promoters of shade; and, 

 to conclude, no style is more appropriate for warm countries than the lightest 

 Italian. I trust these hints may cause some of our professional gentlemen to 

 found a new style of building, by which thousands of our countrymen may be 

 benefited, if they will communicate their designs to your Magazine. — W.

Different Species and Varieties of Corrceas. — Your correspondent, An 

 Amateur, in enumerating the different species and varieties of corraeas (p. 42.), 

 overlooked Mr. Milner's different crossbred seedlings, with the exception of 

 his original variety (which is to commemorate his name), C. Milnerw. C. 

 rosea has already been advertised for sale, and C. cordata is noticed in several 

 periodicals ; besides which, Mr. Milner is said to possess many other seedling 

 corraeas, of his own raising. Nearly two years since, I registered the cir- 

 cumstances under which 1 obtained a batch of hybrid corraeas, between C. 

 speciosa and C. pulchella, and the converse. All these varieties springing 

 from the same common parents, would lead the common observer to expect 

 them to be all of one constitution and habits, and of the same general interest 

 as objects ofTfloral beauty. Yet such is not the case; and well might my 

 esteemed friend, Mr. Marnock, speaking of C. cordata, remark that we were 

 yet but novices in the art of hybridising. C. cordata comes into flower at the 

 height of 10 in. ; and an excellent judge in such matters (Mr. Glenny) ven- 

 tured a prediction that "it would require good growing to exceed 18 in. in 

 height;" while, at the same time, some of my seedlings show no disposition 

 to flower at the latter height, and they promise to exceed, in stature, any of 

 their parents. All my seedlings, like those of Mr. Milner, have a decided im- 

 provement in their foliage. This difference in seedlings produced from the
