The following conclusions are based on the results obtained during 4 

 years : 



"Early planting of potatoes and frequent tillage to conserve moisture -will ordi- 

 narily give best results, [but] necessitates vigorous spraying with Bordeaux mix- 

 ture aud Paris green to protect the foliage from blight and beetles. 



"Success with potatoes depends largely upon the preparation given the soil before 

 the potatoes are planted. Plowing should be deep and at the time of planting the 

 soil should be mellow aud loose. 



"On soils which are likely to be affected seriously by droughts, it is especially 

 important that the potatoes be planted early and deep, and the tillage should be 

 frequent and level. 



"On soils which are not well drained, either naturally or artificially, aud on clay 

 or clay-loam soils, potatoes may be. planted somewhat shallow and slight hilling may 

 be practiced with benefit. 



"Harrowing the land after the potatoes were planted and before the plants 

 appeared produced marked beneficial results. From 6 to 7 cultivations have given 

 best yields." 



Variety test of potatoes, C. O. Flagg, G. M. Tucker, and J. A. 

 Tillinghast {Rhode Island Sta. Rpt. 1897, pp. 381-388).— The method 

 of carrying on the test is described and the results are given in tabular 

 form. Brief descriptions are given of the new varieties used in the 

 experiment. 



In 1896, 11 varieties of potatoes were tested, and the following season 

 5 of these varieties were given a further trial and 10 new varieties 

 were grown in addition. Enormous, a late variety, produced the 

 largest total yield aud marketable crops in both seasons. 



Cultural experiments with potatoes, C. O. Flagg, G. M. Tucker, 

 and J. A. Tillinghast {Rhode Island Sta. Rpt. 1897, pp. 322-351).— 

 The results reported show the effects on the yield of potatoes (1) of 

 spading the soil to depths varying from 4 to 18 in., (2) of very thorough 

 and less thorough cultivation, and (3) of planting at varying distances. 

 The experiments were conducted for 2 years in succession. The aver-
