results or the experiments With S''soN is an instructive and interesting pam phlet. Tn the test of thirty varieties Cooks Improved stood at the head of the list in total value of seed and lint. Browns Improved, a selection from the variety just named, stood second. Layton and Moss occupied thrld anu { fourth places; 1t should be noted that in the experiments at Auburn ,nese two varieties were classified as belong ing to the Peterkin type. Southern Wonder held the fifth and Toole the sixth position in the Georgia test m 1905.
 Of even greater value than the re-
 ports of yields for any one year are the averages for twelve years giving certain details for those varieties stand
 ing in the upper half of the list In
 point of yield and for those other vari-
 eties occupying the lower half of the list in this respect.
 For this twelve year period the best half of the varieties averaged SA.7 per cent of lint against 32.5 per cent TOT the poorer varieties
 Tbe hest half of the varieties aver aged 70.1 boils per pound of seed cot | ton against TAT bo1ls per pound.in the | Inferior varieties, thus suggesting that | in the long run the large-bo!i varieties have been most productive, However, there have been notable exceptions 70
 this rule in certain years.
 1 In six years the best varieties nad | larger seed and in six years smaller seed than the less productive varie- I ties Earliness was advantageous Tn l only three years out of the twelVe, namely in 1894. 1895. and 1901, when 1 the early varieties stood in the upper part of the list. During the other nine l years the most productive varieties averaged later than the unproductive varieties. This confirms the conclusion | arrived at by earlier experiments at l number of stations that with cotton, as with most other plants, earliness 1 is not conducive to large yields.
 Col. Bedding suggests that there IS special need to improve the size of the | boll and even intimates that 1t may be possible to obtain bolls so large that ] sixteen of them would make pound i of geed cotton. I seriously question l whether 1t vii be practicable to in- crease the size of bolls beyond that or ] the present big boiled varieties ana
 yet have the cotton mature in tlne . so | partially escape the ravages or the | boil weeyiI. the presence of which after
 A few years must be taken into account Il in all our plans for the improvement or 1 the cotton plant by breeding.
