auxiliary in the business of enriching it with trees : it is the gentlemen of the 

 county, and those in possession of large tracts of landed property, who must 

 be expected to achieve this. Would they, instead of planting their ten or 

 fifteen acres annually, triple or quadruple the quantity, much would be done, 

 in the course of half a century, towards rendering the country far more interest- 

 ing and agreeable than it is at present. The small town which is situated at 

 the bottom of the Mount is inhabited chiefly by fishermen. The nets, or 

 seines, as they are called, which they use during the pilchard season, are of 

 immense length and depth ; and, in corroboration of what Mr. Main says 

 (IX. 723.), it is customary to send them to the tan-pits every season before 

 they are used, or rather to boil them in an infusion of bark, in large cop- 

 pers for the purpose. It has been hinted to me that no good is gained by 

 sending garden nets to be tanned ; but I doubt the truth of this. The opinion 

 on which it is founded may, I think, be accounted for by the fact, that most 

 garden nets are nothing more or less than old fishing-nets, nearly worn out 

 before they are purchased, and consequently their strength is too far spent to 

 be restored by tanning. Were garden nets to be bought in new, I have no 

 doubt that frequent tanning would be of great service. However, fishing- 

 nets have the advantage over garden nets, in being less exposed to the action 

 of the weather : the former are only used in the season when the particular 

 sort of fish they are intended for makes its appearance, and are afterwards 

 carefully dried and laid by ; whereas garden nets, independently of their being 

 more frequently in use, are generally taken less care of. The town of Mara- 

 zion, which faces the north side of the Mount, is perhaps the warmest, in 

 winter, of any town we have in England, being completely sheltered from the 

 north winds by the rising ground in its rear, which shelves down so as to 

 expose it to the south in such a way as to receive all the advantages of the 

 sun's rays. The influence of these rays there is equal to that at many other 

 places where the sun is at a much higher degree of altitude : this, in con- 

 nection with its southern situation, renders the temperature always mild. 

 From these local advantages, handsome bouquets of double hyacinths, anemones, 

 jonquils, violets, &c. can be gathered at Marazion nearly a month sooner than 

 in the places adjacent ; whilst China roses may be seen almost perpetually in 

 bloom. Many annuals, also, such as mignonette, sweet alyssum, &c, often 

 continue in blossom throughout the winter. — T. Bulger. Shortgrove, April, 1834.

Paint combining Colour with Durability. — I should be glad to be informed 

 by one of your chemical correspondents of the kind of paint, combining colour 

 with durability, which is the most appropriate for painting conservatories, 

 forcing-houses, &c. : also, by mixing lampblack with white lead, in order to 

 obtain a lead colour, if strength is added to the consistency, or otherwise ; 

 and if otherwise, what ingredient is considered as efficient to neutralise the ill 

 effects of the lampblack ? — T. Rutger. Shortgrove, May, 1834.
