a potato in each cup and drops it into a tube throuirli wliioli it passes into the 

 furrow. The furrow is dug aliead of tlie seeder and the seed is covered by a 

 pair of inclined disks. 



In the tests it was found that on the average about i hectare (0.61 acre) 

 could be planted in an hour in a field 250 meters (820 ft.) long. No injury to 

 the seed was observed. While it is concluded that such a planter is practical 

 and useful, it is estimated that on a field of 15 hectares (37 acres) the costs of 

 machine and hand planting will be about the same. It is thought probable, 

 however, that a three- or four-row machine of this type on a larger field would 

 cause considerable saving. 



Points on the selection, adjustment, and care of farm machines, E. M. D. 

 Bkacker (Oregon Sta. Bui. 133 (1915), pp. 48, flvs- 37). — Tliis is a popular dis- 

 cussion intended for the farmer and dealing in detail with factors relating to 

 the selection of farm machines, tyiies and adjustments of farm machines, and 

 the care of farm machinery. A number of practical illustrations and other 

 data are included. 



The dairy bam and milk house, how to construct them, R. E. Hundektmark 

 and A. B. Nystrom (Washington Sta. Popular Bui. 95 (1915), pp. 40, figs. 22). — 

 This bulletin describes and illustrates the shed, open shed, bank, and t^\'o- 

 story types of dairy barn, and a convenient milk house, all of which are con- 

 sidered suitable for Washington conditions, and gives instructions as to design 

 and construction, together with bills of materials. 



The construction of shearing sheds and yards, compiled by J. W. Mathews 

 (Dept. Agr. N. 8. Wales, Farmers' Bui. 91 (1915), pp. 29, figs. J7).— This bulle- 

 tin describes and illustrates two sheep-shearing sheds, a combined shearing 

 shed and grain store, and sheep yards for small flocks, and points out the fac- 

 tors to be considered in their planning. 



Housing farm poultry, A. G. Philips (Bien. Rpt. Kans. Bd. Agr., 19 (1913- 

 IJf), pp. 656-669, figs. 21). — The substance of this article has been noted from 

 another source (E. S. R., 27, p. 374). 



Planning the farm in relation to the farmstead, J. B. Davidson (Bien. Rpt. 

 Ka7is. Bd. Agr., 19 (1913-1. 'f), pp. 35S-3G0, fig. i).— The author offers a sketch 

 showing the routes to be traveled in performing the farm operations, this to 

 serve as a basis for the best location of farm buildings, roads to the field, 

 fences, etc. 



Household conveniences and how to make them, C. E. Hanson and E. J. 

 Fermier (Texas Agr. Col. Ext. Serv. Bui. B. 8 (1915), pp. 27, figs. IJf).— This 

 bulletin describes and illustrates cold water and hot and cold water supply 

 systems, a fireless cooker, evaporation cooler, cold bos, fly traps and screen 

 frames, ironing board, and kitchen wall cabinet. 



Saving fuel in heating a house, L. P. Breckenridge and S. B. Flagg ( U. S. 

 Dcpt. Int. Bur. Mines Tech. Paper 97 (1915), pp. 35, figs. 3). — This bulletin de- 

 scribes the different fuels used and methods for heating residences, discusser: 

 factors affecting the design of heating apparatus and governing the consump- 

 tion of fuel and the convenience of operation, and gives general suggestions on 

 the firing of different fuels, together with the results of house heating tests 

 obtained from various sources. The most important points brought out in 

 this study are as follows : 



"... Both convenience of operation [in heating a house] and consumption 

 of fuel depend on the system of heating (and ventilation) installed, and con- 

 venience, fuel consumption, and first cost should be considered in making a 

 selection. The heater should be large enough to meet continuously and without 

 attention for periods of eight hours the demands for heat in all weather except 

 the most severe,
