202 The Woburn Field Experiments , 1904. 
Trifolium incarnatum {Lansome Field), 1904. 
For the last few years crimson clover ( Trifolium 
incarnatum) has been grown with considerable success at the 
Woburn Farm, and made into hay, which has been used by the 
farm horses. The ease with which the seed can be sown, viz., 
on a corn stubble, by merely scarifying and harrowing the 
ground and scattering the seed broadcast, makes it a crop that 
can be readily put in, and as, after it, there is time to sow white 
turnips or mustard, it makes a very good “ catch crop.” Up 
to this year the crimson variety had always been sown, but 
it was decided to try in 1904 the white variety also. This is 
known as Trifolium Molineri , and is generally believed to 
give less produce than the crimson variety. It is later in 
growth than the red, and the seed is also dearer. The two 
varieties were tried side by side in Lansome Field in 1903- 
1904. The Trifolium followed wheat. Both varieties were 
sown, 20 lb. of seed to the acre, on September 1, 1903, and 
harrowed in. The crop in each case came up well and stood 
the winter capitally. The early red variety came into flower 
on May 23, 1904, and was ready for cutting on June 13, being 
carted on. June 22. The late wdiite variety was cut on June 
22,* and carted on July 1. The respective weights of hay 
were : — 
T. c. q. lb. 
Early red Trifolium . . . 3 3 2 21 per acre. 
Late white „ ... 3 2 0 21 ,, 
Thus the difference between the two was not great, though 
there is no advantage for the white variety, especially as the 
seed costs more. It may, however, be convenient to grow the 
two kinds, in order to be able to follow on from one to the 
other, and not have the whole ready at the same time. The 
crops were excellent, and did good service for feeding cart 
horses in the winter. 
Experiments on Pasture. 
1. Laying Down Land to Grass ( Great Hill Bottom ), 1903. 
The field, having been grazed in 1903, was hayed in 1904 ; 
it was, however, treated as a whole, except that the two new 
plots, laid down in 1901 with Mr. R. H. Elliot’s mixtures, were 
separately weighed. The grass was cut on June 21, and carted 
June 24-26. The yields were : —
