In addition to comparative tests of the various remedies for the San Jose 

 scale, wliicli liavc been jjreviously reported (E. S. It., 19, p. 56), cooperative 

 experiments in si)rayin}i for the second hrood of codlinji moth were carried on. 

 The i)lats were injured l>y tlie freeze of October 10, thus destroying the chance 

 of gettinj: accurate results, but tlie evidence secured indicates tliat tlie si)rayinfj 

 should 1)0 done by Auj,'ust 1. It is recommended that in orchards infested with 

 the codlins moth the trees should be sjirayod with arsenate of lead either the 

 latter part of ,Tuly or early in August. With varieties subject to the attack of 

 ai)plo scab the addition of Bordeaux mixture is advised. 



[Beport on horticultural crops of the Upper Peninsula Substation for the 

 years 1905 and 1906], L. M. (iioisMAR {Miclii<i<ni Ktti. i^pec. Bui. -'it, pp. Ji2- 

 59). — Cultural and varietal notes with tabular data in some instances are given 

 of peas, bean.s, sweet corn, cucumbers, squashes, i)umpkins, mnskmelons, onions, 

 tomatoes, radishes, spinach, lettuce, cabbaire. celery, pepper, tobacco, and kale, 

 together with several herbs, honey plant.s, and ornamentals grown at the station 

 in lilO.l and T.KKJ. Sinnlar notes are given for strawberries and orchard fruits. 



Report of the horticulturist, F. Garcia ( Wetv Merico &'?«. Rpt. 1907, pp. 31- 

 JiO), — An outline of the work of the year with data on variety tests of sweet 

 ]K)tatoes and the cost of producing sweet ])()tatoes and chillies. The newer 

 work includes variety tests of ajiplos and strawberries, a study of the life his- 

 tory of the codling moth and a test of the lime-snlphur-wash for the San .Tose 

 .scale in that region, investigations relative to the best time to ])lant stniwborries 

 and onions, and fertilizer and close-]ilanting celery tests. 



The ."> best sweet jiotatoes relative to yit'ld were the Polo, Fullerton Yellow 

 Yam, and I'.razllian. In I'.HKi on a one-half acre plat of sweet potatoes, the 

 total cost, inclusive of hauling the crop and growing the sets in the cold frame, 

 was .$40.07. 'i'lie total yield was 1(»,.S(»!) lbs., which were sold for $15n..3r.. 

 Partial data are given on similar work with sweet potatoes and chillies for 

 1907. 



Report of the horticultural division, F. W. Card (Rhode Island *S7«. Rpt. 

 1907, pp. 21 1-21 'i, 220-265, pis. 7). — The results for the year are given of various 

 cultural and l)reeding experiments, including further data on the market garden 

 rotation and lawn experiiiients (E. S. R., 18, p. 112.5). 



A large number of crosses have been made between different varieties of 

 raspberries and blackberries during the past years. Some general notes are 

 given on a few of these which are considered promising. 



The breeding of beans with a view of increasing their frost-resistant innver 

 was continued and the results to date are given. To determine what progress 

 has been made in increasing the hardiness of the lieans, seed of the same varie- 

 ties included in the work was obtained from a seedsman in 1907 and i)lantod 

 with them. From the data obtained the conclusion is reached that this is not 

 a iiromisiiig line of jiiant breeding. 



Further observations are given on the C(mdition of the various plats in the 

 lawn ex])eriments in which the effects of fertilizers leaving an acid residue and 

 those leaving an alkaline residue are being compared with fertilizers having :i 

 neutral effect on the soil. Seven different grasses and grass mixtures wore used 

 in this comparison. On other plats different ])roportions and combinations of 

 fertilizers are being tested, together with si)ecial grass mixtures offei'od by 

 seedsmen. 



In the market garden rotation experiment, in which the value of stable 

 manure is being compared with chemicals combined with cover crops, potatoes 

 and early cabbage were used for the early crops, which were followed by beets and
