ill the proportions of one bucketful of lime to three of water; 

 and, in the tan around the edges of the bed, by stirring powder 

 lime into the infested tan. Insects have been eradicated from 

 young pine plants here by immersing them thirty-six hours in 

 water medicated with soft soap, in the proportion of four ounces 

 to a gallon. 



We are extremely careful at all times to supply any want of 

 heat, air, or moisture, and control their extremes ; as also to 

 remove all obstacles that might hinder the full action of light, 

 especially in winter : to effect which, we are obliged, sometimes 

 more than once, during winter, to take off the lights, and clear 

 away a green glutinous substance that collects inside about the 

 laps of the glass ; using a scrubbing-brush and a piece of coarse 

 flannel, with plenty of water, for the purpose. 



We never tie up the leaves of pines in moving the plants, 

 being persuaded that the leaves of any well-grown pine plant 

 cannot be tied up without injuring them : neither can the height 

 of a plant be so well determined, nor the side that has been 

 inclining towards the sun so well reversed in plunging, when 

 the leaves are tied up, as when they stand in their natural 

 position. 



Jamaicas are esteemed here as being the best for maturing 

 perfect fruits in the winter months. The plants of this species 

 are of lazy growth, impatient of disrooting and shifting, and not 

 easily started into fruit before they attain a good size. Their 

 fruits, also, are heavy in proportion to their bulk ; and, unlike 

 many others, they will swell their pips flat at all seasons.
