fuel wood ; of the second grove, 3,038 first-class and GIG second-class 

 posts, and 4.8 cords of fuel wood. 



A plantation in Sangamon County, 111., in which the original 

 spacing was 4 by 5 feet, contained at 21 years of age 800 trees, with 

 a yield per acre of 1,920 posts, all first class, and 4.9 cords of fuel 

 wood. The cost of establishing a plantation in Illinois under present 

 conditions is about $15 per acre. 



A 17-year-old plantation in Washington County, Iowa, in which 

 the trees had been set 4 feet apart each way, was found to contain 

 1,312 trees per acre over 4 inches in diameter breast high. The 

 average diameter of these trees was 5.7 inches, and the estimated yield 

 of the stand w r as 2,778 first and second class posts per acre. The effect 

 of the quality of the soil upon the yield of catalpa is well sho\vn by 

 a 21-year-old plantation in Iowa County, Iowa. The original spac- 

 ing of the trees was 9 by 5 feet, and on good soil there remained 524 

 trees per acre which had a diameter of 4 inches or over breast high. 

 The estimated yield was 1,896 posts and 96 poles. A portion of the 

 ,stand which was growing on a sandy knoll contained only 380 trees 

 per acre, with a yield of but 572 posts. 



A 25-year-old plantation in Nemaha County contained 747 domi- 

 nant trees per acre, with an average diameter breast high of G.G 

 inches, and an estimated yield of 1,829 first-class posts, 845 second- 

 class posts, and 1.9 cords of wood. 



In York County, Nebr., whrch is near the western limit of the 

 range for economic planting, a 21-year-old plantation contained 406 

 dominant trees per acre. The average diameter of the trees \vas 4.7 

 inches, and the yield was limited to 242 first-class and 140 second-class 

 posts, and 0.4 cord of wood. 



In a plantation in Paw T nee County, Nebr., the owner kept a strict 

 account of all expenses incurred in establishing, maintaining, and 

 harvesting his plantation, and of the final proceeds. The seedling 

 trees, at $1.15 per thousand, cost $3.13 an acre; the preparation of the 

 ground, planting, cultivating, and pruning cost $18.46 a total of 

 $21.59 per acre. At 5 per cent compound interest this was increased, 

 in the sixteen and one-third years during which the plantation grew, 

 by $26.34. Cutting and marketing the crop added $61.90 per acre 

 to this, so that the full cost at the end of the experiment for the 20 

 acres was $2,196. 



The returns were : 



31,397 third-class posts, at 5 cents $1, 569. 85 



17,349 second-class posts, at 10 cents 1,734.90 



4,268 first-class posts, at 12* cents 533. 50 



270 first-class posts, at 15 cents 40. 50 



211 8-foot posts, at 20 cents 42.20
