TOPOGRAPHY OF CHINA. 107 



That the S. west portion is cut off by the great Pe-Ling, 

 which enters China at 34 N. lat., and the Yun-Ling 

 entering in at 31 N. lat., and descending southward 

 to the Province of Yun Nan ; and another ridge in the 

 opposite direction, N. N. east, entering Shen-Se. The 

 Ta-Paling intersects the country from W. to east to 

 115 East long., and the Nang-Ling runs off from the 

 north to 150 miles of Canton, and then inclines N. east 

 to the 30 N. lat., or Nan-Po, having given out many 

 branches, some of the mountains belonging to which rise 

 above the snow line. 



The above will show, that if in 29 of N. lat., or green 

 tea district, so much care has to be taken of the plant, 

 that upwards, or at least north of 30 N. lat., owing to 

 the great altitude as well as the increasing cold from the 

 natural causes, that the country is unfavorably severe 

 and hence the plant becomes a green house curiosity at 

 Pekin, 40 N. lat. Again : If we proceed southward, we 

 find that the Nang-Ling starts off from Ningpo 29 30 

 N. lat. and long., 121 30 until it nears Canton by 150 

 miles. Canton is N. lat. 23, and long. 113 25 , so 

 that we are cut off by that diagonal range reaching above 

 the snow line. If we go down to Amoy, N. lat. 24 , 

 Ball says the teas, for the most part, are inferior. But 

 the price current will show them to be almost valueless. 

 And again, the Waping and Honan teas of Quang-Tong, 

 in which is situated Canton, 23 N. lat., &quot; may be given 

 as examples of still greater inferiority.&quot; Below, or south 

 of the 27 N. lat. there is no good tea produced ; and, in 

 fact, N. lat 28 and 29 and part of 30, may be put 

 down as the good tea districts. Gutzlaff says, u the 

 extent of the soil, the best Bohea, is not more than 40 ly,
