house had the slight advantage of getting any sun there was r 

 whereas the experimental house in winter was almost completely 

 shaded from it, therefore on days when there was bright sunshine 

 the temperature in the former house rose slightly higher than that 

 of the latter ; the average temperature of the two houses was 

 for the first three months of the year : 



Except on the days with brilliant sun the average day temper- 

 ature was from 50 to 63 in both houses. The lamp was put on 

 about sunset and kept alight for about five hours. 



Lettuces, carrots and cauliflowers responded to the treatment 

 in a remarkable manner while the lettuces in the control house 

 never came to maturity and the carrots were fully three weeks 

 later. 



Some of the cauliflowers, when showing their centre leaves, 

 were planted out of doors in raised beds surrounded by 6in. 

 boards ; for the first three nights glass lights were put over them, 

 the next two a mat was laid lightly on a few stakes above them, 

 after which they were left unprotected, and though there were 

 nine degrees of frost two nights later they were not in the slightest 

 degree checked, and produced finely shaped heads fully a week 

 earlier than those of the same age, raised in heat and grown after- 

 wards under normal conditions. 



Strawberries responded remarkably well to the treatment. 

 There was a profusion of bloom and the fruit set well, the plants 

 bore fully 25 per cent, more fruit than the control plants, and 

 were 10 days in advance of them, but unfortunately the plants 

 in both houses became affected by white mildew just as they were 

 colouring, which rendered the crop unfit for picking. 



One or two pots of vegetable peas were sown in December, of 

 which the following table gives the result :
