VARIETIES OF COTTON- 1905 and 1906. W. R. PLKKJNS. N reprt was published f the variety test f cttn fr H)05. Owing t the date at which the ginning was dne, it was deemed useless t make such a reprt t late t be f any service fr the fllwing year. The results f the eximent fr 1905 and thse fr 1906 are included in the fllwing brief reprt. The test f varieties has been cnducted fr the past fur years n the same piece f land. The sil is f medium quality and varies frm a light t a rather heavy lam in places. N fertilizers f any kind have been used n the land during the fur years except abut ten lads f barnyard manure in tlie spring f 1905. This was spread ver the prer spts as a means f bringing all parts f the sil t a nearly unifrm state f prductiveness. livery precautin was taken t avid any divisin f the land int plats that wuld give any variety f cttn an advantage ver anther in the way f being n better land. The varieties are always planted in ne-rw plats, and repeated a number f times, usually abut ten times. Instead f ne variety being gruped in ne part f the field it is scattered regularly all ver the area. In the test fr 1906 every sixteenth rw was in the same variety, there having been sixteen varieties planted. The tables fllwing give full data as t yield, value f crps, etc.:

In calculating the value f crp, shrt staple cttn is reckned at 10 cents pund, lng staple at 15 cents, and ne and ne-furth inch staple at 12J cents pund. Seed are calculated at 60 cents hundred, r $12.00 tn. The price given t shrt-staple cttn represents fairly what it wuld have brught dui'ing either seasn, thugh a discriminating market might have made sme small differences, due t varying length f staple. The lng staple if anything wuld have brught mre than 15 cents pund, s that fr the tw past years, at least, the figures shw abut the differences existing in value. The data in tables need little cmment, further than t emphasize the care taken t prevent any cnditins ther than the difference in seed, entering as a mdifier f the results, and t call attentin t the fact that sme varieties f cttn are nmch better than thers. In 1905 the difference in value f crp between the prest yield and the best was $26.81 acre, and in 1906 a difference f $19.25 existed, r mre than the average ttal yield f an acre ver the entire state, r ver the entire cttn belt. The better yields were made at exactly the same cst as the prer save that f gathering and ginning the excess f prductin. In the crp f 1906, if the prest crp had been made and marketed at a ttal cst f $30.00 there wuld have remained as prfit $16.41. The cst f the better yield wuld have been $30.00 plus the cst f picking and ginning 325 punds f cttn, r abut $2.00, making the ttal cst f this crp $32.00 acre, and leaving a prfit f $33.66, r mre than duble the prfit frm the prer variety. It is nt t advertise ne r mre varieties f cttn r t disparage anther that this cmparisn is made, but t emphasize the fact that such differences d exist and that as ne f the factrs f better farming the subject shuld nt be disregarded.
