 ft. high, with a head 13 ft. in diameter. When we saw it, Aug. 10th, 277 

 blossoms were expanded at once, producing an effect upon the spectator 

 under the tree, when looking up, which no language can describe. Last 

 year it produced successions of blossoms, in one of which 600 were fully 

 expanded at one time. This year it has had five successions of blossoms, 

 and another is now coming out as the plant expands in growth. There 

 is a large Brugmansia coccmea in this house. Both these plants are in 

 the free soil.
