(2) Great care should be exercised to luaiutaiii a vigorous growth (Vom the start. 

 and particularly to avoiil injury from insects and mildew. 



(3) In this latitude English lucumlxrs produce marketable fruits from the seed in 

 from 80 to 100 days. 



(4) The plants must be trained. Two or three strong arms may be allowed to 

 each root, and these should be 8top]ied as soon as they reach the sjiace allotted to 

 adjoining jdants. Part of the young growth should be removed, and in midwinter, 

 especially in dark houses, some of the leaves may be removed to advantage. 



(5) The fruits should not be allowed to lie upon the soil, and the heavy ones are 

 sometimes supported in a sling to prevent injury to the vines. 



(6) Siou House, Telegraph, Kenyon, aud Lome are good varieties. The fruits, 

 especially of the longer sorts, are usually marketed before they attain their full 

 size. 



(7) The English forcing cucumber has been produced by selection from shorter 

 and spiny field sorts within recent times. 



(8) Hand pollination appears to be essential upon the first flowers ; but cucumbers 

 set and mature with no polleu whatever, though in that case fruits are usually 

 later and probably fewer. Pollination must be employed when seeds are desired. 



(9) Seed bearing is not necessarily associated with deformity of fr'uits, although 

 upon some plants it appears to conduce to the production of swollen ends, which, 

 however, appear to be avoided by swinging the fruits. 



(10) The spotted mite and aphis {Aphis rumieis ?) can be destroyed by Hughes's 

 Kir Tree Oil, and the powdery mildew (Oidiuvi ert/siphoides, var. cucnrhitarum) is kept 

 in check by fumes of sulphur and by the ammoniacal carbonate of copper.

 account of the second and third years' experiments with wheat on the 

 same plats, the object being to test the profitableness of using fertili- 

 zers for wheat on Ohio soils, and the special needs of the soil for this 

 crop. The land used contained 22 tenth-acre x>lats, separated from 

 each other by intervening strips 2 feet wide, and had been in clover in 

 1887. The fertilizers applied per acre each year were as follows: Dis- 

 solved bonel)hick 320 pounds, muriate of potash 160 pounds, and 

 nitrate of soda KJO pounds, were used alone and combined two by two,
