been in leaf for some days,&quot; and seed-sowing had begun. 

 In 1841, seed was sown in open ground, April 8th. In 

 1842, pie-plant broke ground March 8th, and all early seed 

 were in the ground by the 21st. In 1843, seeds were in by 

 April 20. In 1844 ground was in a working state Feb. 

 23d, and seeds put in by March 1. Trees, varying according 

 to the nature of the season, complete the first growth, on an 

 average, about the 1st of September. Their second growth 

 continues, usually, into November. In 1844 we had noisette 

 roses pushing out terminal leaves after Christmas; but this 

 is not a frequent occurrence. Upon an average, the middle 

 of March and the 1st of November, may be taken as the 

 limits of the vegetable year a period of more than seven 

 months. During this season rains are copious, and fre 

 quent. Our midsummer droughts are seldom so severe 

 upon vegetation as they seem to be in New England. 

 During the months of June, July and August, the tempe 

 rature of mid-day seldom falls below 70 Fahren. and 

 ranges between 70 and 100. 



One other cause of rapid growth is to be mentioned 

 the nature of our winters. Except when the roots are 

 frozen, they are supposed never to be inactive. During the 

 winter they slowly absorb materials from the soil, and fill 

 the whole system with sap. When the winters are severe^ 

 they are usually very long ; and the slowness of its winter 

 action is compensated by the length of time afforded to the 

 plant. In the western States, though the winters are short, 

 yet there is scarcely a week in which trees may not accumu 

 late their stores. The spring growth will be vigorous in 

 proportion to the amount of true sap collected in the vege 

 table system. As the whole winter is mild enough for 

 this process to go on, the growth of trees is rampant in 

 spring. Thus, the quality of the soils, and the nature of 

 the seasons the mildness of winter the earliness of spring 

 and length of summer its heat and great atmospheric bril 

 liancy, all conspire to produce very rapid and strong
