Gardening is not much encouraged about Carlisle.; but it will doubtless receive a stimulus from the improvement which that town and its neighbourhood may expect from the railroad now constructing between Carlisle and Newcastle; and which, it is estimated, will be completed in three or four years from this time. Between Carlisle and Dumfries, there are few opportunities of gardening, from the unfrequency of gentlemen's seats. There is a gardeners' benefit society of Liverpool, which Mr. Rollis informed us is one of the richest, in proportion to the number of subscribers, in the kingdom. Its rules and regulations are about to be confirmed, according to the act of parliament respecting benefit societies; and, when this is done, we are promised a copy for publication. The Walton Nursery library is in a most flourishing condition; and the books are now accessible, at very easy rates, to all who are desirous of perusing them.
