number were beeches and oaks ! For such extraordinary 

 success, in restoring and continuing vegetation after removal, 

 I chiefly account, from the care and regularity, with which 

 the water was distributed, and the valuable discovery, that 

 so cheap and common a substance as shows has the property 

 of excluding air, and retaining moisture, and is, by conse- 

 quence, the best safeguard against the effects of drought. 



The next branch of afterwork, that requires consideration, 

 is a very important one, and that is the maintenance of the 

 trees in a state of progressive vigour, after being planted: 

 and, as there are few subjects in arboricultural economy, that 

 appear to be less understood, I shall the more particularly 

 enlarge upon it. 



It has been already observed, that no experienced planter 

 expects his removed trees to shoot freely, until they have 

 been fairly established in the ground ; and that is a circum- 

 stance, which must be regulated by soil and climate, by 

 scientific planting, and pi'evious selection. It is true, accord- 

 ing to the system now attempted to be established, they will 

 carry a full leaf after the first, or, at all events, after the 

 second season ; and, as they are preserved entire in all their 

 parts, they will produce the full eflfect of trees, which have 

 never been removed ; still it is not until the fourth or fifth 

 year, or more, that shoots of any consequence can be ex- 

 pected. With particular trees, however, this expectation is 

 not always fulfilled ; and it sometimes happens, when the 

 process of removal has been conducted in the best manner, 

 and on the best soil, when the sun has shone, and the rains 

 have descended most favorably on the plants, that six, and 

 seven, and a greater number of years will elapse, without 

 any decided proofs of advancement. Not but that they 

 seem sufficiently healthy, and continue to grow ; but we 

 want something more ; we expect them to thrive in their 

 new situations. This backwardness in trees, as it appears, 

 is confined for the most part to suoh as are planted in exposed
