" Highly as I appreciate the Mexican guano, still I do not hesitate to say that I would 

 rather have four tons of Colombian than ten tons of Mexican, and I would rather have 

 equal portions of Colombian and Peruvian applied to any wheat than Peruvian alone, or 

 any other superphosphate alone."

 small quantities may now be procured. We recommend its trial by farmers and horticul- 

 turists. For the Pear-tree it will be invaluable. 



Flora of the Colosseum at Rome, is the title of a London volume, by Dr. Richard Deakin. 

 The author says that 420 species of plants are found growing upon the Colosseum, including 

 253 genera, and illustrations of 6G of the natural order of plants. There are 59 species of 

 grasses, 47 of the syngenesious plants, and 41 of the pea tribe. This is in an inclosed space 

 of six acres of ground, a limit that does not include the walls and ruins. This space includes 

 a great variety of soil and temperature. The lower north side is damp, while the upper 

 walls and accumulated mould are warm and dry ; and the south side is still hotter, and 

 more Italian. Strange miitation that one of the most innocent and poetical of the sciences 

 should now choose the Colosseum for its favorite haunt, where the swarth Egyptian, the 

 agile Moor, and the crisped-haired Nubian, struggled and died amid the shouts of Romans, 

 uproarious in their holidays, the more delighted, the more savage the scene ! 



BEURRfi Capiaumoctt Pear. — A correspondent writes: "I have been much edified, nay, 

 instructed, by Dr. Ward's chapters on Pears. I believe the Duchess d'Angouleme bears 

 more abundantly, in a young state, on the quince than any other kind, except, perhaps, 

 Beurre de Capiaumout, which, wherever I have met with it, shows its decided preference for 

 the quince, by uniformly producing large crops of very handsome and good fruit on it." 



Travel and Health. — The Virginia Springs. — If one of the great pleasures of travel is 

 novelty, and observing changes in modes of life and modes of thought, the Southerner should 

 undoubtedly come Northwards, and the Northerner visit the South. The change affects the 

 observer as much as a trip from London to Brussels. We speak the same language, but our 

 usages are vastly different. A residence of a few weeks at the various springs of Virginia, 

 offers inducements to the healthy of this kind, with a cool atmosphere, and a mixing with 

 polite and agreeable peoj^le, whose thoughts, however, run in a refreshingly new channel, 

 that leaves out much that we glory in — such as love of stock securities, and a never-ceasing 

 talk of money. The railroad from Alexandria will carry you, this season, to the very doors 

 of the Rockbridge Alum Springs, now all the fashion, where a good table, and a gentleman 

 to administer to your society as well as comforts, give attractions of superior order. Then 

 these Alum Waters do really cure some of the worst ailments of our fragile race. 



A short ride by good stages conveys you to the Warm Springs — a bath in whose waters 

 you will never forget, and a seat at whose table is a treat, even to the boarder at the Girard 

 House. A little further are the Red Sweet, the Sweet, the Healing, the Hot Springs, and, 

 further on, the Salt — a capital place, and, near by, the fashionable White Sulphur, where 

 stages by the dozen arrive full of people who know perfectly well they must sleep on the 

 floor ; but fashion is omnipotent, and you must be seen there if you want to get a partner 

 for life, or expect to be able to converse for tlie ensuing winter. A day's ride then brings 

 you to the Red Sulphur, famous for curing consumption. 



For our own comfort, we should be perfectly satisfied with the Rockbridge Alum, and 

 could settle down there, for the season, on its venison and hot bread, making excursions to 

 the Natural Bridge and the Peaks of Otter, without any regrets for tide-water or lobsters. 

 There is here a daily mail, and a well-managed post-ofiice. People wlio have never tried 

 this summer atmosphere, have no proper notion of cool America in hot weather.

Grapes, of the Isabella kind, may be kept till March, by packing them in boxes with 

 alternate layers of ash-wood sawdust, and keeping them from frost. The boxes may be 

 set one on the other, without any other covering. The sawdust of the ash imparts no 

 flavor to tlie fruit.
