192 VEGETABLE PHYSIOLOGY. [DEC. 



LETTER XII. 



December 3. 



I HAVE really so little to add to my directions 

 for the last month, on the subject of the garden, 

 that, as we are to meet soon, I should not have 

 written again, had you not especially desired 

 that I should send one more letter on the sub- 

 ject, to add to the eleven I have already sent. 

 I am well pleased by the care you have taken 

 of these, and I hope they will be useful as a gar- 

 dening manual. I recommend, however, that 

 you should, from time to time, add your own 

 observations, and the results of your experience 

 to them. If this be done with care, you will 

 soon obtain a valuable stock of information. 



My principal object has been to call your at- 

 tention, generally, to the subject of gardening
