ture, or the effect of the sun's heat in causing evaporation. I give my large 

 camellias generally double the quantity of water that gardeners are disposed 

 to allow. But, I believe their healtliy appearance depends very much upon 

 the liquid manure, and water from the cess-pool, diluted about half and half 

 with rain water ; give them, perhaps, once in the fortnight, and at this sea- 

 son, wlicn they are in a state of vigorous youth, once a week. The same 

 treatment is applied to rhododendrons. The mould for tliem should be one- 

 half sandy part, one-third loam, and the rest of rotten leaves, with some river 

 sand. I think it is of great advantage, though rather offensive to the eye, 

 to spread over the surface of the earth in the pot or tub, cakes of half-rotten 

 leaves. These tend to keep the surface moist, and also afford excellent 

 nourishment to the roots. I believe one half of the plants that perish is 

 owing to a neglect of proper draining and inattention to watering when the 

 plants require moisture. This is piirticularly tlie case with tlie tribe of 

 Ericee and also of camellias. I never lilie to see a plant hanging its ears, 

 and telling a careless gardener that he is neglecting to give it its necessary 

 nourishment. If the roots are allowed to remain too long in a dry state, 

 they will infallibly perish. I do not recollect if you observed some fine 

 specimens of the Pinus Cembra. I have two or tliree, about 15 feet high, 

 and a noble plant of the Pinus Pinaster. — [Id., 1850, p. 283.) 



In cases where prunary expense is deemed secondary to ultimate effects, 

 2 lbs. of tlie evergreen wood meadow-grass may be added to each of the 

 above columns ; and where the ground is shaded by trees, both Poa neimr- 

 alis and tliat variety should be substituted for similar quantities of the two 

 Ftscues, sucli quantities being dependent on the extent and depth of tlie 

 shade. 



In walks, bowlmg-greens, &c., which are wished to be kept as dry as 

 possible, especially towards the end of the season, Trifolium repens should 

 be sparingly introduced ; and when it is intended to mow the grass by ma-
