thus removed not only took well, but had the advantage over 

 those planted when very young, as is customary, in growing 

 stronger as well as being sooner fit for use. If the success 

 of this experiment should be confirmed by experience, it 

 will relieve the gardener from much labour and trouble in 

 attention to the planting his trenches of Celery at an early 

 period. 



At the Meeting on the 3rd of August, a Communication 

 from William Cotton, Esq., of Wellwood House, near Ley- 

 tonstone, was read, detailing the effects of an experiment in 

 washing an old garden wall with seal oil, with which Anticor- 

 rosion paint* was mixed. He had first used the mixture for 

 the purpose of colouring the bricks of a new wall near a flower 

 garden, and having an old wall contiguous, on which the trees 

 had been blighted, and nearly unproductive for several years, 

 he washed it with the oil, mixing a small quantity of the paint 

 with it. In the seasons which have succeeded the operation, 

 the trees on the old wall so coloured have borne good fruit, 

 and made strong wood, whilst those on a much better wall 

 in another part of his garden, having the same aspect, which 

 had not been painted, were much injured by blight. This 

 wall he has since washed over with cod oil and a small quan- 

 tity of Anticorrosion paint. The cod oil was used as being 

 less offensive in smell than the seal oil ; the effect has been 

 considerable, but the cod oil does not appear to be so great 

 a preservative against blight. 



* This material is sold by Mr. Roger Jones, Robert Street, Hoxton ; its 

 composition is a secret, but it is stated to be made of highly vitrified mate- 

 rials. It is prepared in powder of three different colours, stone, lead, and red, and 

 is principally applied to covering fences, and out-door buildings.
