pods. The yield from a small planting of 4-year-old vines averaged slightly 

 more than 0.5 lb. of cured beans per vine, with an approved valuation of from 

 $3 to $4 a pound. 



Report of the horticulturist, C. F. Kin man (Porto Rico Sta. Rpt. 1911, pp. 

 20-24. pis. 2). — A brief report on progress made with various lines of work 

 during the year (E. S. R., 38, p. 748). 



In the fertilizer experiments with coconuts that have been conducted for 

 several years the last application of fertilizer was given in June, 1916. The 

 number of nuts collected from the plats given a complete fertilizer fell off 

 somewhat at the last harvest, as compared with the check plats, thus indicating 

 very little permanent benefit from the fertilization. A survey of the coconut 

 plantations of the island was inaugurated during the year with a view to deter- 

 mining the most profitable practices. 



Seedling trees of several varieties of East Indian mangoes fruited during 

 the year. Among these, none except seedlings of the Cambodiana variety bore 

 fruit which resembled the parent variety at all closely. All except the Cam- 

 bodiana seedlings had a high content of long, tough fiber, while the parent fruits 

 were practically free from fiber. A survey made during the fruiting season 

 showed that along the north side of the island and through the higher interior, 

 where there is considerable rain during the blossoming season, the mango crop 

 was small, as is usually the case in these sections. Through the western and 

 southwestern sections, where the winter drought continues well into the spring, 

 there was usually a good crop of fruit. This survey Indicates the necessity of 

 selecting locations with reference to fruitfulness. 



During recent inspections through the citrus sections of the island it was 

 observed that the effect of the lack of fertiliser was already apparent on the 

 trees of certain groves. The author points out that the need of a fertilizer 

 rich in potash in these sections has been well established by experiments 



In December. 1910, 1G varieties of sweet potatoes received from the Bureau of 

 Plant Industry, V. S. Department of Agriculture, were grown simultaneously 

 with plantings of the same varieties received from the same source in 1911, 

 the latter having been in cultivation in Porto Kico for nearly six years. The 

 quantity and appearance of the potatoes produced from plants of one importa- 

 tion did not vary to any great extent from those of the others, hut all v. ere 

 markedly inferior in texture and flavor to the seed material received from the 

 Bureau. A thorough study is to be made of the apparent deterioration of 

 northern types when grown in Porto Kico. In continued tests made with Porto 

 Rican types, a variety locally known as Blanca has been found to produce roots 

 which are superior to any of the lately introduced northern varieties both in 

 texture and flavor. 



Notes are given on the behavior of miscellaneous introductions under observa- 

 tion, including Crotalaria taltiana, Tabebuia spectabilis, Corypha sp., and 

 plants of the East India sugar palm [Saguerus soccharifer) .
