Nave or Noix du Lot. The Nave or Noix du Lot resembles the 

 Corne both in shape and in appearance. The shell is clear, ovoid, quite 

 pointed, slightly projecting along the line of suture of the valves in 

 the upper half ; the shell is tough and hard to crack ; it is less wrinkled 

 and more uniform than the Corne; it is much less elongated at the 

 apex and more flattened in the region of the point. The Nave is of 

 average size; it measures 39 to 40 mm. in length, 29 mm. in width. 

 The average weight of a dry nut is 8J grammes and the weight of a 

 hectolitre 36 to 38 kilogrammes in a good year; in 1910 the weight 

 was only 34 to 35 kilogrammes. The nut of Lot is very precocious and 

 always comes in a dozen days before other varieties. It is much 

 appreciated for commerce and exportation for the two following 

 reasons: Because the hard shell allows it to sustain handling without 

 breaking and arrive intact in America; because it is harvested early, 

 which permits the commencing of shipping about the 15th or 20th 

 of October, while the other varieties are not ready for exportation till 

 in November. They cultivate it in the environs of Cahors and in the 

 south of the department of Lot. 



The Noyer du Lot blossoms late, May or June; they harvest the 

 nut to the end of September; the merchants buy the dry nuts from 

 the producers. Discarding the culls, they sulphur the nuts and send 

 them to Bordeaux and to Germany. 



Lelande. The Lelande is elongated, terminating at the apex in a 

 very pronounced point; the shell, very irregular and deeply sinuous, 

 is unsymmetrical at the base and a little flattened. The line of suture 

 of the valves is very projectile, especially in the middle. This nut 

 has a shell of clear color, thin and very tender, breaking easily; it is 

 unsuitable for transportation. The fact that its kernel is fine and 

 plump makes it a choice nut for commerce, put up in boxes and for 

 sale as green kernels. The average dimensions are as follows: length 

 41 mm., width 30 mm. The average weight of a dry nut is 9 grammes 

 and a hectolitre of dry nuts weighs from 35 to 36 kilogrammes. 



The Lelande is cultivated principally in Correze and Dordogne. In 

 certain parts of Correze this variety is replaced by the Marbot, which 

 is more productive, larger, having a shell a little harder which can 

 stand transportation ; the Marbot also sells for a little more. 



The tree attains an average size; it is very vigorous but it blossoms 

 early which makes the crops irregular. The yield is large when the 

 late frosts do not destroy the flowers. The Lelande nut sells on an 

 average of from 15 to 20 francs per hectolitre; in 1910 the price 

 reached 37 to 40 francs ; in 1900 it was worth from 10 to 12 francs and 

 in 1909 from 20 to 22 francs. A hectolitre (2.85 bushels) of nuts 

 makes from 15 to 16 kilogrammes (33 to 35 pounds) of kernels con- 

 taining 50 to 55 per cent oil.
